To ask what is the most sneakiest, underhanded thing you have ever done and why?

[Bellatrixurstrange]

I threw a load of DD4 and DD9's toys away earlier in the month as they have faaaaar too much stuff and I was de-cluttering.After swimming, DD9 asked where X, y and z toy were and I said I had no idea. I do. At the charity shop. Oops. Feeling guilty now. Has anyone else ever been sneaky or told a white lie or been underhanded and then felt abit shit afterwards?

Me and a friend were both totally in love with a boy in primary school, in year 4 a new girl started and they were immediately boyfriend and girlfriend. She was very pretty and we were 7 and jealous so after stealing some of their school books to copy their handwriting, we wrote notes to each of them pretending to be the other one saying you're dumped. It worked, we were evil.

I anonymously provided confidential information that got my ex boss jailed for commuting fraud against the govt.

It was such a stressful time and I've never spoken about it to anyone but I couldn't sit on the information I had and not do something.

Go you Maitland.

I also once anonymously reported an arsehole landlord to HMRC for tax-dodging as he was definitely dodgy, rent in cash etc. Hope the scumbag is in prison now

This is the sneakiest thing I never did, although I was very tempted.

Ex-fiancé was moving into our "forever home" with new woman, so I had to move out. Very good friends had many suggestions of what I should do, but I didn't do any of them in the end, because he assumed I would, so I didn't give him the satisfaction.

Best suggestion was dead rat in the water tank - unfortunately, only way to get one was from a pet shop, and that would have been a white rat, not a feral rat, so it would have been kind of obvious it had been placed there (assuming they found it before it turned into decomposed rat soup).

Anyway, didn't do it. Did take the new carpets though. And the light fittings - but left the wires safely despite Dad not wanting me to!

I might have eaten a whole box of Dh's favourite birthday chocs. Then denied seeing them so he thought he'd accidentally thrown them out.
In high school I really fancied the best friend of my best friend's boyfriend. Me and friend decided it would be good if we got together at end of year dance.Another girl started making moves on him, so we got her in huge trouble in school and got her banned from dance. (Wish I hadn't bothered as he was dull as)

I one scratched my sisters limited edition cd. Felt very proud of myself until she put it in the CD player and it still bloody worked. So had to suffer months more boyzone.

Is the BIL your DS's husband or your DH's brother? I'm trying to decide if it makes a difference!

Mine was before I married DH and not sure if it's in the spirit of the thread by here goes...

Had been dating a guy for about a year. All good and I felt our feelings were deepening slowly, no reason to think otherwise. Out the blue when out for a meal he said "I haven't been entirely honest with you..." For months he had been searching for his lost love and had found her! The one thing he had omitted to do was tell me and only when he'd found her did he think he ough to fess up! I was heartbroken but went quietly.

Fast forward about 4 years. He made contact again. It hadn't worked out with the love of his life. Could we meet again and talk. I allowed him to think he had a chance with me again without leading him on, I was sparkling fun . I let him woo me, pay for meals, take me out, I was charming and desirable and he was desperate to get me back in bed.

I cold heartedly played a game and let it go on until crunch time came and it was time to tell him I'd been messing him around. He outright asked if he could take me away for the weekend and obviously spend the time getting jiggy. I smiled sweetly and calmly made the best speech of my life as to why it was never going to happen. His face was a picture and there was nothing he could say! Never saw him again after that.

God I was a bitch in my twenties...

Told my mum my brother hadn't been going to extra revision classes in the run up to his GCSEs - he'd been hanging round mcdonalds with his mates.

It was a complete lie - my poor brother had been working very diligently after a shaky start in year 10, but it sounded so believable!

Luckily he found it funny rather than being angry

Many years ago I was in a relationship and found out he was married, he had a lot of stuff at my house which I bagged up to return, including a brand new games console.
I took it apart and cut every wire I could find and carefully put it back together
I'm not sorry

I loooove your style.

Not sure if underhand but decided i didnt want to continue seeing my boyfriend for loads of reasons as i didnt feel it was right for me. Id try to break it up but im not good at that. I knew he would be hard to get rid of as has stalker properties (a reason i didnt want him). Looked around and saw a friend of a friend who was single. Spent next couple of weeks encouraging himto pick this girl up to take her to an event i couldnt go to etc. you be amazed how many times i throw them together. it worked as shortly afterwards he two timed me with her. . I was able to get out of the relationship and had amazing summer seeing family members and getting my work sorted so i made it to uni. Meet dh in the autumn of that year. I believe ex is still with that girl so hopefully they are happy together. Im afraid thats as understand as i can be as you kinda get what you get with me.

An ex bf from many moons ago who was EA, FA and DV took great delight in waving in front of me the six festival tickets he'd purchased with the last remaining credit on our last credit card. I of course was not invited to the festival, but the other girl he was sleeping with and her cronies were.
Imagine his rage when halfway up the motorway to said festival he found there were only five tickets in his wallet. The other one had mysteriously vanished in to a million pieces in the bin at work. Luckily I'd planned my exit that weekend so never had to deal with the rage face to face. It was the scariest/best thing I've ever done.

Underhand not understand i get. Felt awful re the support i got from friends to him.

split with exh (he cheated) couldnt afford mortgage on my own so he was going to move back in with ow when i moved out , to make it more homely for them i let my dog piss on every carpet , put dog food under the floor boards , poured milk in the sofa , left the heating on full whack then left , told him he could move back the next week , then he phoned said the place stunk so i convinced him it was the drains and he paid someone to come and look at them :)

DDad developed dementia and I moved him in with me as I was worried for his safety. I let his house. I managed the letting myself but had the tenant vetted via an agency. I had masses on my plate with my DDad so took my eye off the ball spectacularly with the tenant and it wasn't until I had a call from DDads old neighbours about her that I went to see for myself (giving her due warning that I was coming etc. I treated her professionally from the beginning).
Words cannot describe what met my eyes so I gave her notice. I am not talking chipped paintwork here, I am talking ripped out fittings for burning in the winter, the lawns 6' high with weeds, broken windows, old car parts strewn around and everything filthy, drilled and damaged.
She stopped paying immediately and it took me months to get her out. I turned up there the day after she moved out but DDad (when he had been well) had cut a small hole in the garage door for a feral cat to get in and get warm in the winter and I noticed something red on the other side of the hole so opened the garage to find all her possessions in there. She was clearly planning on getting them very soon so I called a mate with a massive van and the lot went to landfill within two hours. This made me irrationally happy

Mine is sneaky, but not really underhanded. My DH (he was my BF at the time) and I had sex in a hotel room with his Mum in the room. It was a hotel room with two queens in one room. We were on one queen and his Mum was on the other. I think she had fallen asleep.

Also when my DH (again BF at the time) came to stay with me in my parents house we told my Mom that he was sleeping on a mattress in a separate room, but every night he came into my room and we slept together. She never found out.

She never found out.

You think! she probably knew all along!

I daw red when I got dumped and my heart was broken so I removed the fuse from every electrical item I could and took them with me,

My OH brother

These are making me howl with laughter! I'm impressed and in awe at the same time. I think I better get abit sassier in my naughty forties as I haven't got the guts to do even half of this!

I did steal someone's marble bag when I was in infant school though. "Clara" had the most beautiful marbles in a red velvet bag and when she won my favourite marble off me I thought I'd get her back. I was just a jealous child but when she discovered it "Clara" told the headteacher who gave everyone a bollocking about it in assembly and read a corresponding Bible passage about theft to rub it in further. Fast forward two days later, riddled with guilt and the bag minus my favourite marbles was magically discovered in "Clara"'s PE bag, much to her embarrassment.
Headteacher made her apologise in whole school assembly for wasting everyone's time. Poor "Clara". Jealousy and envy can turn the nicest of girls dark. All over some shiny pretty marbles. Insanity.

CuteCat we need more information! We're you with your oh at the time?! What happened afterwards?

Resurrecting an old name so as not to tie this to me currently...

In between finding out about XH cheating and him moving out we had a period of pretending to be still together before we told the DCs. This meant that I had to put up with him carrying on with OW whilst I still cooked / did his laundry and worst of all as we had no spare room, I had to share a bed with him.

A few nights I poured warm water over his boxers in the night so he woke up thinking he had wet the bed. He put this down to the stress of "having to live with me"

I poured water in the carpets of his beloved classic car that he was going to restore but found out that he couldn't as water was mysteriously getting in and made the body rust.

I took his laptop cover off and had a little play about inside and broke it and he lost loads of work that the hadn't backed up.

Strategically cutting a few threads on his shirt buttons caused them to pop off and his shirt come open whilst he was running some training sessions so nice and public.

On discovering that his new gf had bought him a watch, I took one of the links out, threw it away and put the watch back together so it didn't fit all of a sudden.

I didn't want to do anything blatant like grass seed in car / cutting up his clothes etc that would obviously be down to me as I wanted to have an amicable relationship in the long term (which we now have) but still wanted to make myself feel a bit better.

Awaits flaming for gas-lighting ex.

After (yet another!) fight with DSis when we were teenagers, I added a large dollop of salad cream to her bottle of facewash... She did notice it looked a bit yellowy and smelled funny, but only after she'd used it for a week or so!

I waa 18, my ex was a useless weed addict and I spent a year doing everything for him. He blamed his shit behavior on his ADHD. One of the things I did was write his application for uni, so I had the password. When he cheated on me for about the sixth time, I logged onto UCAS and deleted the offer he had from his favourite university.
