What’s the worst thing you’ve ever done?

I’m in a reflective mood, and it’s got me thinking about something I did a few years ago which is probably the thing I’m most deeply ashamed of.

There was a coworker who really rubbed me up the wrong way. I was very unhappy at the time, and going through an awful time personally. She would make snide comments about me, do things with my family members (who were colleagues too) which really got my back up, I felt like she judged me harshly and was pretty rude. Along with another colleague they made three or four very nasty comments which still stick with me.

Instead of raising a grievance, which I should have done, I took to posting about her on another website (along the lines of Mumsnet), not realising she used it too. She saw the posts and reported me, and I ended up facing a meeting with HR and a senior partner of the firm I was working in. It damaged my reputation within the firm forever and I ended up leaving after not being offered a promotion. I still feel ashamed of it now, nearly half a decade on, and feel like it’s tarred me forever.

Whats the worst thing you’ve ever done?

Funnily enough, I've been thinking lately about some of the things I did when I was younger and they don't reflect very well on me at all. Ultimately I only have myself to blame but I do wish I had been given more attention and moral guidance when I was growing up.

When it comes to a lot of things I’m very much an advocate of not judging things from the by the standards of today…so really if you lacked that moral guidance in the past something you did then is arguably ok.

I see your 2 men and raise you one man and one woman (separately) on the same day. I wish that was the worst thing I'd done in my life...

Well, I also surprised my awful grandmother with a loud "Goodnight, Granny!", deliberately making her jump.

She died 10 days later.

So that was pretty bad. Sorry not sorry, she made our lives a misery.

I have been with my Husband, since I was 19, now 45 and I have a really good marriage.

In my 20s when I was pregnant, and a bit psychotic! We had a great big row and I dipped his toothbrush in the toilet! He is a right germophobe and even though I didn’t tell him at the time I was hugely smug with myself!

I did confess a few years ago, and he was absolutely horrified!! I don’t regret it though, I think it’s absolutely hilarious. My younger adult children looked at me like I was absolutely insane at the confession time.

Reminds me of the story told by my nanna, a stay at home mum to 4 under 6, got confronted by my granddad who asked why some tiny little household chore hadn’t been done. She launched his plated dinner straight at his head! She left the stain there for two months to remind him not to try that again 😂

I put fish in parsley sauce, mashed potato and peas into DH’s posh shoes.

Probably not the worst thing, but it was memorable.

Marvellous.

Yeah I think it’s quite telling that the worst thing OP can think of is that she didn’t handle a bullying situation as well as she might have.

OP, you’re not perfect, and that’s ok 💐

I had a short affair with a married man who I was good mates with at work, I was actually in love with him, his wife was not in the country & i knew he’d had other affairs. But in all conscience i couldn’t stop thinking about his wife so i stopped it.
Anyway, his wife moved here & they had another child, he’s still a Facebook friend but lives elsewhere in the UK.

But thats not the shittiest thing I’ve done that i really regret. There are a couple of things I can’t even talk about really but I deserve bad karma.

Not sure if having a poo outside as I was desperate is better or worse than an affair.

You’re in good company. The utterly amazing Paula Radcliffe did that in the London Marathon.

MayaLui · 20/04/2026 18:14

Had a row with my sister on her wedding day about how I felt she'd excluded me from the day. We were very close and I was a mess about her getting married - felt like I was losing her, was upset about our family changing shape. I totally lost my mind, no excuses. We patched it up and are close again many years on but I still can't believe I behaved so abominably and it did a lot of damage to our relationship for years (and I don't think her husband will ever think much of me).

I handled it awfully and it still makes me sick to my stomach and I cringe with embarrassment!

That and the fish-in-shoes story sound like they have a detailed back story 🤣

EineReiseDurchDieZeit · 20/04/2026 18:16

I broke someone’s heart very badly. I was in a difficult and stressful situation and I acted thoughtlessly. I still feel like shit about it

GrueyTwoey · 20/04/2026 18:17

Pissed in a pint glass abd threw it out of the window.
I was young, and drunk.

I appreciate I don’t know the full story, but she could have done some self-reflection rather than going straight to HR. Just saying.

iamfedupwiththis · 20/04/2026 18:18

Got drunk and wet the bed

This wasn't me but i didn't discourage it either...

Computers were a new thing when I was at school - total of about 5 computers for the whole year.

Everyone was allocated a computer terminal, I was e.g computer number 3 and roughly 8 people were to share the same one that year. No logins or passwords, just a folder each for us to save Higher English essays on.

Coincidentally I used the same one as the nastiest bully in the whole school. (Verbal and physical violence, even put her own Mother in hospital).

'Someone' accidentally deleted all of her essays just at the point she was due to submit her stuff to the exam board.

Ooops it was obviously an accident though

wellerrrrrm · 20/04/2026 18:23

I was mean at school. I used to hide things after PE so my friends couldn’t get changed. I have no idea why. I hid my friends pyjama bottoms on a sleepover - I really feel bad about that; she was lovely and have no idea why I was so spiteful.

MerelyPlaying · 20/04/2026 18:24

Went back to my home (still paying the mortgage) after separation from my husband to collect some stuff and found the OW had moved some things in and was clearly staying there if not actually living there.

i used their toothbrushes to clean the toilet. And then I diluted some of her shampoo and shower gel bottles with a little bit of piss. Actually I’m not sure it was a bad thing - it made me feel much better.

Yellowpapersun · 20/04/2026 18:24

My horrible grandmother remarried to an even more horrible man. He used to try to feel mine and my girl cousins' thighs and told me to open my mouth when he kissed me. I hated him. They used to come round one evening every week and I used to offer to make the last cup of tea before they went home. I used to spit in his cup, every single week. Over the years he must have drunk a gallon of my spit.
When he died my boyfriend and I went for a drink to celebrate. My friend was in the pub and I told her Uncle Sid was dead and she said Hooray! 😂

If it's any consolation I did LOTS of things when younger that don't reflect well on me and I had attention and moral guidance when growing up.

I think doing questionable things is just part of growing up and learning to 'adult' so please don't be so hard on yourself.

Nollie · 20/04/2026 18:26

Aw thanks @Additup

MycactusandI · 20/04/2026 18:26

Stole from my parents' coin jar and bought loads of sweets. My mum worked out what I had done and the girl i was playing with was banned from seeing me.

I also had lots of dubious hook ups at uni and in 20s. Had a particular thing for attached men. I used to think it was all due to low self esteem, now I think it was more of a dopamine chasing mission (although they prpbably go hand in hand)
