My cousin used to bully me; he was adopted by one of my aunts. Whenever I'd visit my grandmother he'd be there, in part because my aunt wanted us to grow up together/be friends or whatever. Instead he'd constantly attempt to embarrass me, or hit me. At the time, my grandmother lived with my uncle, and he has a big house with a huge backyard in Detroit. It was a fun place to be during the summer. My time there was split between playing Street Fighter 2 and exploring outside, and my cousin fucked both of those things up. Basically I'd kick his ass in SF2, then he'd kick my ass outside because he was pissed. And not in terms of us wrestling or anything. I'm talking about me climbing a tree having fun by myself, then him throwing logs at me or trying to pull me out the tree. Or running as fast as he could and pushing me from behind. Punching me out of nowhere, then being all like "sorry man, I was just having fun lol."
Every summer I'd go to a Sunday bible camp at my grandma's church, and my cousin would come too. One year there was this girl at the camp that he really liked, but was too shy to talk to. He asked me to tell her how cool he was, and I told him no. He'd ask me to do this every day, grabbing my arm and shit. Finally one day during lunch he pushed me from behind, right onto the table the girl was sitting at. I was covered in food/juice and was about to tackle him, but an adult separated us. Not one fucking person came forward and defended my story that I was pushed, and I wound up getting punished after I wouldn't apologize for trying to hit my cousin.
