My first real fight was in 8th grade, I fought with my neighbor (same age) for some stupid reason whatever. Just a couple punches to the face exchanged and we fell to the ground when his dad broke us up.
Towards the end of 8th grade some friend was mad that I was talking to this girl he liked (I liked her too but as a friend). He called me and told me to meet him at the local elementary school park. I had like 8 friends with me at the time so I was definitely peer pressured right into it and I was pumped even though I assumed I was going to lose. He was like 40 pounds heavier than me and had an inch or two advantage. When I got there we talked stuff and he ran at me, I backed up 2 feet and right when he came into range I punched him in the nose really hard and jumped to the left and he fell to the ground. He got back up and his nose was bleeding like hell and I punched him some more. He never got a single punch and his friends pulled him away.
Last one was Freshman year, this random kid came up to me talking stuff and I pushed him back. He kicked me (lolwut) and I took off my backpack and went at it. Onslaught of punches on his face, nose bleeding all over my flannel and hands. The typical group of people surrounding school fights made it seem awesome and I kept going. I let him get back up when I wrestled him to the ground. He got up and 2 more punches he was knocked out. I later learned that at that exact moment, another fight was happening like 50 feet away so that's why no deans came to me. I casually picked up my backpack and strolled away feeling like a champ. One of my friends recorded it on his iPod, and everyone I walked by was jumping on me and giving me high fives.
I didn't get caught until an hour later in English :P that about concludes my history of fights.
