How to get rid of an anoying creep who's stalking me?

Thi creep from the library was sitting next to me, when I was at the library trying to print out some papers and he's always taking a chair next to my computer and like sitting down next to me and he's so frickin old at least 40, and not only that but he's way too ugly. And now i get why he can't get women his age because he's so frickin creepy and ugly so he has to target little girls like me. I'm not scared, hell no, I'm not because I always tend to roll my eyes and ignore that creep, and he keeps reading his damn book like it was no frickin deal and then sometimes he keeps looking up at me, but I pretend he doesn't exist. And yesterday, I went on another computer in the library but he follows me there and its anoying as hell. I don't want to talk to him so can you think of another way to get that scary sh*t away from me???
