Creepers at the mall

okay so back when I was in my first year of high school there was this one (wired) boy in one of my classes, he would often sit next to me and would always try to be my partner during projects. I would always so no but ended up being partners with him anyways :/ anyways he tried manhandling me in the halls one day and I yelled at him for it, he stopped doing that but what really crept me out was that he said to me that he wanted to... get... me...  yeah I'm not going to finish that sentence  I haven't seen this guy sense then but a couple of weeks ago I had to go pay my cell phone bill once I got done with that I went and did some shopping and just as I was going to get on the train he passes me by. I didn't know who he was till after he said something to me. I didn't even stop I just kept on walking, I just wanted to get the hell out of there lol
