<human>: Summarize the given text in a few sentences.

I'll start: I had known this kid for a few years that was a complete asshole to everyone. He had no friends but he continually just talked shit to everyone he encountered. It truly baffled me. People would say stuff back but nobody ever got physical with him out of fear of getting in trouble. (This is when I was in the 7th grade) Everyone was absolutely sick of this kid's shit so one day, in the locker room, He said something to me and I pushed him. We pushed each other back and forth until I just let loose on him and hit him about four times in the face repeatedly and then he backed up and kind of fell to the ground. He eventually got back up but since he was pretty mentally unstable, I went and told my coaches on myself because I didn't know what he would do. I got a day of suspension but after that day, I have never seen that kid again. I went to school with him every day for about 4 years prior to this. I have repeatedly searched him on every social media site but I haven't found the slightest trace of him.
<bot>: In the 7th grade, I got in a fight with a kid I went to school with for 4 years and I haven't seen him since that day.
