Do you have a friend whom you never wanted to know in the begining?

Met him in grade 6. Somehow he was already jacked like a marvel superhero. He beat up a teacher. Was a bully for a few years. I got into a fight with him on the school oval. I think he broke a few of my ribs before the teacher came round the corner. And when he came back from suspension. He decided he and I were mates. And we still chat to each other on facebook.
