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?

Lots more occurring to me now. When I was young (teens/early 20s), I behaved really awfully in relationships when I felt jealous/insecure (which was often, as I grew up without really any maternal warmth or nurturing). On one level, I look back and think I must have looked a right twat, but also I try to have some empathy for the young woman I was, acting out because she just wanted to be loved. Not at all wanting to excuse my behaviour, just wanting to kind of give that young girl a hug because she was really hurting.

I repeatedly cheated on a boyfriend. We had 5 year relationship from when I was 17-22, and I cheated on him prolifically for the first 3 years. I really did love him, but I wasn't mature enough for such a serious relationship. He had suspicions but I would lie my way out of it. I realised the error of my ways and behaved myself for the last two years, but the relationship was tainted with suspicion and I eventually lost him. I've never forgiven myself for it and I've never cheated on anyone since.

I misread the beginning of this as ‘I put bleach in my abusive ex’s eyes’ and was just about to be genuinely aghast after a thread of generally meek misdemeanours!

I’m sure he looked adorable in his mottled, stonewash-effect uniform.

I thought at first that the poster up thread put weedkiller ice cubes in her neighbours' drinks, presumably typing from her cell in HM Prison! 🤣

I feel like this too. I regret many thoughtless things I said when younger, that would’ve hurt others’ feelings. I may be a much better person now, after years of reading, learning, reflecting, but I am paying the price in lost childhood/ potential friendships.
But if you’ve met my mum and older siblings you’d know why I was the way I was.

You and me both x

That’s my opinion, obviously others will feel differently. Why post on this thread, which is about the worst thing you’ve ever done, if it’s not a bad thing?

i don’t know, as I’m not that poster. I assume she’s been brainwashed by patriarchal ideas about a woman’s morality residing in her vagina.

My daughter graduated 2 years ago. She's shy and very quiet and she struggled to find a job. I' was worried about her and wanted her settled. In the meantime, I got her working in my admin team at work in a local authority via an agency. I manage the admin team though don't directly line manage them. Weird set up but worked out perfectly.

I knew that a new role was being created which is a higher grade than the admin officers in my team. I gave my daughter full access to restricted areas meant for senior management and trained her fully in my role and also in everything for the new role. I wrote the job description tailoring it to the tasks my daughter does and to her strengths. The admin team only knew about it 6m before it was signed off. They requested to see the JD but were refused.

I fobbed off any requests for training from the admin officers in my team only focussing on my daughter's development. Poor things, asked so many times, lol. The job was advertised and my daughter obviously got it..She is now a senior member of my team and we work alongside each other.

The job is pretty good and will probably set her up for life in a very nice department in a good field. When I retire, she will take on my work.

Jesus. The cheek of your “lol”.

This is exactly how I feel too. I’ve put a lot of work into reflecting and trying to be a better person but know that my family never will.

It’s morally a completely neutral thing to have done. Assuming everyone involved was consenting and adult. Why do you imagine it’s ’morally not good’?

I put bleach in my abusive exes washing detergent on the day I left him whilst he was at work.
I'd love to have seen his face after his black work uniform came out the wash!

Maybe ,but the pp says she works for the local authority

There can be a lot of restructuring,with people being moved around
Things are not guranteed and with out mummy to hold her hand the daughter may juat find she has bitten more than she can chew.

We can only hope.

Don't we all do twatty things in our late teens/20s though? I can remember some horrible thoughtless things I said which make me cringe looking back, and I also slept with some idiotic guys, was careless about breaking hearts, and upset some of my friends unnecessarily. I regret all of that but I do know I am a better person now, probably because of it.

It works with dandelion seeds too……place a few in the tray before freezing…..pop the cubes out and harvest dandelions to your heart’s content 😜😜

Mangelwurzelfortea · 21/04/2026 13:41

I used to live with a guy (in a two-bed flat - we weren't friends, it was just a flatshare) who had a massive jar of pound coins outside his room and I used to steal them to pay for my bus fare to work (I was extremely skint at the time). In my defence, he was a massive twat who expected me to cook and clean and got stroppy when I didn't, and also tried it on with me. The ceiling fell in over his bed one evening and that felt like karma.

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.

I’m really grateful for this thread. I’ve been going through a lot of self-doubt lately and beating myself up for past mistakes. Knowing that I’m not alone, nobody is perfect and we’ve all done things we’re ashamed of has helped me gain some perspective. Love to all you wonderfully awful people!

And I would add that the people on this thread, with one notable exception, feel remorse for what they did. So in my book that makes them good people!

There are lots of people out there who never give their behaviour (past or present) a second thought. They just do what serves them and hang everyone else, and certainly don't lose sleep over it. And I know from experience that this applies to many people who might call themselves religious, or who hold positions of trust in society.

So don't feel bad! We're all imperfect, but what matters, I think, is how you move on from these things. If you reflect, feel bad and resolve to either make amends (not always possible) or to be better in the future, that's what defines your worth as a person.

People who LOL, however....there's no hope....

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

Always carry a doggy bag

I had sex with 2 men in one evening. Hot summer night in 1974. Never told anyone that.

Really? Deliberately lying about cancer, befriending women to steal their man, stealing, violence.... And this is the worst 😐

It’s more the apparent pride the poster has taken in this which is the issue. The “poor things, lol”. Plus, it ultimately isn’t very helpful for her daughter either. Others on here actually feel remorse for their mistakes and have tried to learn from them.

cheekynamechang3 · 21/04/2026 13:23

ChiliFiend · 21/04/2026 11:44

I 100% agree. Especially "poor things, asked so many times lol." That is really fucked up, laughing at how you treated people unfairly. Frankly I hope her daughter gets messed around in the same way in her next job.

she won't need to as she'll get mummy's job when she retires.
