I went to a 20 year reunion. I was also bullied at school. As oppose to being a large lad I was the tall and skinny type. Since I left school I have put on weight and muscle!
One of the best things I enjoyed about the reunion was stood at the end of the bar were 6 of the bullies. All still together. So I went up to them to say "hello" They had no idea who I was until I reminded them.
A great "picture moment".
As already said I doubt any of them would bother you now. Go or you may regret it.
