I have a problem at my school, there is this one guy that is constantly annoying me, he is invasive, lame, and a person i don't get along.

I think he's trying to get closer to me to be my friend or something, like today when i was doing this programing, and he came over seeing that i was stuck somewhere, pushes my hand off my mouse and tries to help me when i didn't even want his help, but being the polite guy that i am i didn't tell him to get lost, but regret not saying it now.

I find him very annoying to talk to, always stating the obvious and laughs at the slightest thing. Did i mention he's invasive, he stands too close when talking to me which makes me feel uncomfortable and puts his hand on my shoulders often like as if we're close friends.

So my question is, do you guys think i should tell him off, like maybe when i see him next time and say :
"hey, i don't really like you ok, so from now on stop helping me with anything, don't touch me, don't even talk to me"

Or should i just try and avoid and ignore him as to indicate that i don't want to talk to him, this option is however quite annoying cause then i'll be limited to where i go and what i do just to avoid the guy.
