First fight? Grade 3 over pokemon cards. Two kids started shit with me over cards we traded a week ago. First kid rushes me, but I grab him and push him into the second kid who was in mid rush which resulted in the first kid hitting the second kid and busting his lip. Told the vice principal who was standing around the corner and I got suspended for half a day. Luckily, I had a dentist appointment and was going to leave early anyway so lol.
Second fight? Grade 8. I bait one of my friends (let's call him R) into coming near me as my other friend (J) spears him right into the fence. R gets up and starts spazzing and asking who did it. I'm sitting near a tree laughing my fucking ass off and J takes the oppurtunity to lay the blame on me. R pushes me and we get into one of those lame ass pushing fights. I push him to the point where he raises his fist for a punch. Kind of uh, unexperienced so I turned to the side and kind of looked away, but when I realizes he was fucking weak, I counted his punching rhythm and laid a big one in his face after the third punch to my arm. R gets a black eye and goes, "hurr shit doesn't hurt" and tried to make up with me. I made up, but I never let him hear the end of it. Later, during grade 9, we're talking on MSN. He challenges me to a fight, and since his house is on the way to karate (I had karate that day), I decided to go, "fine, let's do it. I'll meet up at your house in 15". I get there and wait for fucking half an hour, kid doesn't show. I ditch and decide to go to karate since he wasn't worth it anyway.
Grade 11? Almost got into a fight. Some kids who have been harassing us since grade 8 showed up at our high school. Tried to block us in the hallway but we just pushed them and walked on. Outside, they waited for us and tried to start shit. One kid grabs my friend (S) and tells him to take off his glasses. S says no, since he doesn't want to fight. Kid keeps pushing him and then decides to randomly headbutt S in the mouth. He just happened to have braces at the time, so he got a pretty big cut. My other friend (P) rushes in and breaks us up, but S is already raging at this point. Kid who headbutted him is boasting to his posse when he looks back at S just to see a hook punch fly at his nose. S breaks the fucking shit out of it. Faggots crowd around their crying friend as we leave. We get to the intersection and they try and start shit with us. I could have punched them and beat the shit out of them, but I decided not too and broke it up. Their bus was coming so they ditched and we just laughed at their sorry asses as we walked home.
tl;dr yes I have.
