Should I end this book at the 100th chapter? Or 125 or 150?

  So earlier at school during lunch, I was sitting with my friends when these two guys walk past and were being really loud so I looked up and one of the guys was watching me. when I looked up at him, he looked at me for a full beat then did this hitler-like salute at me where he extended his arm fully forward in front of him with all his fingers flat out, pointing at me. I got really confused and when he and his friend turned the corner, I gave him the middle finger. Like, what else was I supposed to do though? I still don't know what that was, but it was f*cked up.  

  I DON'T EVEN KNOW HIM. 

Also, Brandon: yeah, I'll be going to the party tonight but only for like an hour and a half. Get Mason to pick me up at 7?
