My school bully
Her name was Jess. We were friends, but she exploited my natural timidity and lack of assertiveness to control me. When she lost her PE trainers she took mine so I had to do the class in bare feet. She used to hide my towel and clothes while I was in the shower, which really freaked me out. Once she stole my knickers, or at least I assume she did. She knew I would never be brave enough to tell a teacher. All day she mocked me gently and reminded me I had nothing on under my skirt. I know now that I was oppressed and humiliated, but at the time I was grateful for her friendship and attention.
