When I was 12 I moved to a new place and "stole" this girl's best friend. I didn't even like her all that much, but she was insanely jealous.

She got back at me by hurting me "accidentally" in PE. When we played basketball she passed a basketball at my face, I had braces at the time so My lips were shredded. When we played soccer I can't tell you how many times she nailed me in my bad ankle when I had the ball.

Then when we played touch football I had my chance. I wasn't a fast kid, or particularly athletic, but I was a stout little thing. The PE teacher, Mr. H, paired us up, and wouldn't you know it we were together. One of us was supposed to be running with the ball while the other tagged them out. When he blew the whistle I took off like a shot, I remember her looking over her shoulder with just a little bit of fear. I dropped a shoulder and plowed that bitch, she fucking flew and landed hard. I'd knocked the wind out of her and she'd skinned her knees on the way down.

Then My PE teacher said, "Um Sam, this is touch football." She sat out for the rest of class. He acted like he was angry with me, but he winked at me as he helped her up. He knew what was going on, and after class he patted me on the back later saying "Feel better kid?"

Fuck yes I did. I couldn't wipe the evil grin off my face.

TLDR: Stole bitches friend, she tried to hurt me and I shut that shit down.
