<human>: So this actually happend about 5-6 years ago. At the time i was 13 years old and not the brightest kid. I would do too much shit without thinking about it and so did the kids around me at that time.  

Without too much backstory, here comes the FU. I was at school at the time and it was lunch break. Me and some friends would aways sit in class playing some browser games at the pc's that would be there and waiting there for class to start. However, we always did stuff that wasn't allowed since there were no teachers there. So we would challenge eachother to do certain things. Here was my turn, someone challenged me to throw a chair at this black kid. The thing is, he knew he would have that chair thrown at him but he didn't how hard it would hit him. And well, it hit hard. Once the chair hit him he stood up and started fucking chasing me around the desks and wouldn't stop. (note: this guy was pretty buffed up compared to me and was 2 years older than me, so he would pretty much fuck me up). After like 30 secs of chasing me, he thought fuck it and jumped over the desk to grab me by my backpack and threw me to the ground John Cena style, once on the gound he kicked the shit out of my backup full of books not hurting me at all (he did fuck up my books though). Once he walked away, it was completely silent and i was just sitting there on the floor confused to what the fuck just happend because he didn't hurt me at all. After that we casually resumed our day like nothing happend.

Can you provide a brief overview of the text?
