My brother is only two years younger than me, so when I was a junior in high school he was a freshman and I was showing him around. He was excited and I was already feeling ready to graduate.

Maybe two weeks in some senior, big dude, seemed smart enough but was somehow too bad to be on any sports teams. I saw the dude around years before and he tried out for loads of teams, didn't make any of them, then bragged about how amazing of an athlete he was and how hard he works out.

Anyway, this dude, let's call him Sam, starts harassing my brother when I'm not around two weeks into school. I don't know about this until my brother comes home with a bruise on his cheek. Big fucking welt. My parents ask what happened, he said he ate it skating home. (We both used to skate home, at different times due to clubs and music shit)

Later when it's just him and I, I ask him what really happened. You don't eat shit on a longboard and only get a bruise with no scrapes. Sam had slammed him with his elbow. I told him he should just tell a counselor, maybe a sheriff, and it'll all go away.

Next day, brother got a busted lip for calling Sam out, I flip my shit. My brother can be a pain in my ass but I love him to no end. I told him that I'd handle this, and nothing more was going to happen.

I gather up a few friends and we throw on some old clothes, scarves to cover up our faces, the whole deal. Note that I was a fairly skinny guy at 6"3', Sam was about 5"10'. My friends were around the same height as Sam and there were three of us. We catch him in the park by our school on the route back to his house because he liked to walk home shirtless. Fucking tool.

Friend one takes his skateboard and socks him in the mouth, knocking him on his ass almost immediately. We kick the shit out of him while he's down there. Friend two knocks him out with a skull punt, keep in mind that my buddies are far bigger than I, actually having been successful athletes. While he's unconscious I stab him in the back of the knee with a pocket knife. I didn't use the whole blade, I wasn't trying to cripple him. It was just the message.

We leave him there and take off.

The next day we had a sheriff coming classroom to classroom talking about what happened and to fess up if they knew anything about what happened. Scared the shit out of me then because I was thinking (and still do) that we went too far.

Two years later, out of high school, feeling awful about the whole thing, but off the chain. I still haven't seen Sam around since that day though.
