Argh I wrote mine and it got deleted!
But essentially, when I was 18/19 I worked in a coffee shop and on my first shift, caught a girl regaling our colleagues with something I had said (perfectly innocuous and just being nice to her) in a mocking way. I was mortified at the time being young and shy but even then I realised it was very much a her problem.
She did turn out to be heavily disliked by the rest of the team and even her 2 “friends” bitched about her incessantly, and her them.
Not aimed at me, but the other bitchiest thing I have ever seen happened Around the same time. I had become best friends with another girl who worked there and we were out at a big club.
She had suffered since early teens with anorexia severe enough to be hospitalised and in a specialist unit. She really came along during our friendship in terms of her relationship with food and our many nights on the town, and she had put on a little bit of weight which was great.
Anyway at said club, we were out in the smoking area and this young man and woman (think it was a gay man and his friend) for some reason still unfathomable to me to this day, decided to ask her if she was pregnant.
I mean, we were both standing there, drink and cigarette in hands. It was incredibly rude and if the answer had been yes, well what would they have done? They must have just been spoiling for some drama.
We are no longer in touch now, but I often think of her and hope she is okay. What a fucking blow that must have been to someone in her position.
