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?

This is bonkers as it's the customers who suffer, not the other staff.

Who's handling the returns???

It's interesting that most of the 'bad/worse' things people have done are sexual or unkindness, harming an animal, usually accidentally. Perhaps it's we women who carry guilt around with us for so long. Can't see many blokes still feeling guilty about a fling years ago.

I had a short affair with a married colleague. Him and his wife were going through the stress of IVF, and he was easy pickings for a single, flirtatious girl. No-one ever found out. They went on to have children, and are still happily married 27 years later. I still think about the hurt we'd have caused her if she had known about it.

How many children did they have and is his wife's initial S?

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.

Nonsense. That's completely stretching.

Find it very hard to believe you hit someone with your car and the police just let you go.

Bloody hell, these are the WORST things?
I still feel so awful about something I did 40 years ago I'm not sure I can even post it on an anonymous forum 😓

I feel seen!
I've never physically hurt someone or ever hurt an animal, but I've definitely done a lot of things I regret that were either stupidly reckless or ridiculously selfish, and a lot of times both.

Aged 16 lied about having a terminal illness. Took it too far. Hurt a lot of people. I was being abused by someone who told me nobody would miss me if I died and stupidly I wanted to test the theory out without obviously dying and in my immature mind it was the only way. It was awful and I got in severe trouble

I do hope your abuser got into far worse trouble.
