When I was in first grade I stole a little blue plastic "counting bear" from a huge bin in my class. It was peer pressure. I told my friend how much I liked the little bear and she said to just put it in my pocket and that no one would know because it was after school and the teacher had left already. I felt so guilty about it even years after. I've had the opportunity to steal many other things sense then, but I remember that guilty feeling so I keep myself in check.
Years later, I actually met up with my first grade teacher and confessed to my crime. She laughed the matter away, but I felt rather upset that she didn't take me seriously. That was years of guilt and she blew me off. I know I was taking the stupid little bear too seriously, but I'm a really good person and crimes and other bad things just affect me like that. I can't help it.
As for having something stolen from me:
Thousands of Pencils, Including several mecha ones that I adored.
Gum and other lunch items... I go hungry a lot...
A fair amount of money from my bank account - my scum father took it, believe it or not.
My Shiny pokemon that I caught without cheating from my silver version, my friend traded it without me knowing it. I hate him for it.
I'm sure other things have been taken from me, but I'm not quite sure what it is at the moment.
I'm sorry if this was a long story, I just felt like sharing. - Forgive me if I'm wrong in posting here...
