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?

How can you not know- didn’t you try to find out?

I wasn’t able to pull over or stop for multiple reasons but I drove to the police station which was 60 seconds drive away, gave them all the details and my information. Never heard anything.

I'm assuming it was accidental? Did you stop?

Definitely accidental! I wasn’t able to pull over or stop but the local police station was down the road so I pulled over when able to and went in, gave all my information the details of what happened. Unfortunately I didn’t have a dash cam at the time.
A lovely police officer offered to drive my vehicle home if I was in shock.
I never heard anything from it. It has been over 10 years.

I have been deeply ashamed of this for nearly 40 years.
I was a new student at uni with very very little money. When walking to a friend’s I found an envelope on the ground.
It contained about £30 and a note saying something along the lines of “here’s what we collected - hope you can use it”. Nothing on the front, no address or anything inside.
My sensible side knows there’s not much I could have done but I didn’t take it to the police, I didn’t knock on doors - I kept it and used it to live on for the next couple of weeks.
I still regret it very much.

Then my guess is that she was all right and, assuming you weren't driving illegally in any way or without due care and attention, they didn't consider there to have been any crime. It's possible she was known to them and/or might have stepped out into the road when she shouldn't have.

Wow, I'm shocked at the utter vitriol and wishes and hopes my daughter fails. To clarify a few things. Firstly this is absolutely true and like someone pointed out, nepotism isn't illegal. Someone even mentioned that it's common in the NHS too. I did nothing wrong. Yes, I trained my daughter up and withheld training from other staff. However, my daughter is very bright. She got a first at university. With a little help from me, she picked it all up really quickly and is doing really well in the role. She isn't lazy or a failure.

When she came here after uni as a temp, I didn't create a master plan about this. I didn't even know about the job until a few months after she started. She was really struggling to find a job. As mentioned previously, she's shy and lacks confidence. She struggled to fit in at secondary school and although uni was a lot better, it had it's own issues. She really struggles with her communication skills. The team are lovely and really friendly and always try to include her. In any other places, id worry she'd get picked on. Here, they are nice and she's under my watchful eye so I know she'll be okay. I suspect she might be on the spectrum. She works hard and this job was perfect for her- doing isolated work on her own working with spreadsheets and data without having to communicate much with people.

If you are parents, I'm sure you'd understand. I'm just worried about her and wanted her settled. It so happened that the overall team manager went in long term sick and subsequently retired, so an opportunity arose where I could train my daughter on senior level work. It's almost like all the stars just aligned. I just wanted her settled in a job. She already struggles in so many areas in her life and I didn't want her struggling in work too.

As for writing the JD, yes it went through all the HR processes but in the absence of the team manager, the HoD asked me to draw something up as he obviously doesn't have a clue about the tasks. I wrote it up and he added a couple of things and signed it off to HR as though he had written it. I wasn't involved in the recruitment/ shortlisting or interview.

I hope this sheds some light on things, it's not always so cut and dry when people do terrible things.

Also to add, it wasn't from me to refuse the rest of the team to see the JD. This was a decision made by the HoD.

That was my thought process as well, every week for 4 months I went into the police station, purchased every newspaper available and joined every local FB page looking for information but nothing.

Forgot to add, the area it happened is a major tourist attraction so lots of CCTV.

Was sleeping with a guy who had a GF for ages. And when I came back from my maternity leave a couple of years after, there she was now working at my work. It was a small place, would talk daily and I would mentor her too.

I set up a fake FB profile and emailed my colleagues wife to tell her he was having an affair. He was an absolute prick - shit at his job, gobby about his affair and turned all of the teams stomach with his audacity of being so open about shagging his OW, this was also his 2nd affair. His wife threw him out and his life unravelled. He had a good idea it was one of us but no idea who which was wonderful. He left not long after and hated us all, I have never regretted it but know it was a bad thing to do.

A popular kid was mean to my DD at school in reception. Really mean, lots of times.
Another child was having a party and told DD she couldn’t come and was also mean.
It was a small type party in a chocolate making place so they only invite a couple of guests but have to pay for all 4 when booking
Anyway mean party girl brought in an invite for meaner friend. The mean girls name is similar to DD ( think Eliza and Elisha eg) so their drawers were next to each other
DD ended up with mean girls’ invitation and I popped it in my pocket to give to her Mum. As I approached the mum the next day saying hi was very unfriendly and snobby…. sooooooo I made up some BS question about the Christmas fair and threw the invite in the bin
Mum put a post in the fb group about how devastated her dd was not to go and blamed the school for not passing out the invites properly
I am a bad person because I dint feel bad at all lol

Not necessarily, if its the same crime 🤔

Always carry a doggy bag

My first thought was "How do you aim accurately into a doggy bag so you can catch the crap?" Oh dear.

My mum was dying and I'd been at her bedside all day. I went to my DS's school play that evening instead of being with her and she died whilst I was at the play. I rationalised my decision by thinking that she was past the point of knowing anyone was there and that my son (who was around 7) would remember me not being there. But the truth is that I didn't want to go back into the hospital. The nurse told me she'd had someone with her as she passed, but I don't believe that. I think she died alone and I'll never forgive myself.

I've done other things such as cheating on partners and been a bit of a bully at various times of my life. However, I've worked on myself and moved on from these episodes (and apologised to those affected). But I don't think I can move on from my mum.

@theworldisadarkplace - people often wait until they are alone, or until their loved ones aren’t there, before they die. In some way they don’t feel like they can let go whilst the people,they love are there.

So I’d say you did the best thing for your mum and your son.

As a mum and grandma myself, I would rather my kids were there for their children, not sitting at my deathbed.

Had a brief “fling” (wouldn’t even afford it the dignity of an “affair”) with a married man. Found out I was pregnant after I ended it. I caused his wife “hurt” because I was a thoughtless, selfish idiot. I will never forgive myself for that.

The worst thing I have ever done which only me and one other person know about is that I committed fraud, I was young and very stupid and I would have definitely been given a criminal record if I had been caught. I feel sick when I think about it, pretty much zero chance it would ever come back on me now but I still feel rubbish about it.

Other things include definitely sleeping around a bit too much when I was younger and not being there for my stepmum when she died. I was a shitty person. I’m nicer now that I’m actually happy and settled.

An old friend of mine, maybe 20 years ago, sat telling me how she was filling out her DLA or ILA forms and trying to milk it for as much as she could. She got the top amounts of disability support - but guess what? She was perfectly healthy. So I reported her. And she lost it all. I never felt bad for that if I’m honest

Myli1 · Yesterday 21:06

Probably not the worst thing anyone’s ever done, but not really advisable - last year whilst on holiday one night I walked back from a cocktail bar totally naked all the way through town and back to the hotel. To be fair we were staying in a naturist hotel, but the bar and town are not within the naturist urbanisation.

When I was eighteen I was a bit of a tearaway, drinking cider and smoking weed, hanging about with a bunch of people who all did the same, anyhow ended up in jail for my eighteenth birthday, for about nine months, the scary part was, looking back, it didn't bother me, but it did upset my mum, when I got out I still carried on with my reckless lifestyle, but never went back in the nick, and now I'm a teacher....wait I'm not sure which part is the worst....

I told a new group of friends I knew someone who’d had their arm broken by a swan (I don’t). 36 years later we’re still friends and I live in constant terror one of them will ask me about it.
