<human>: Can you give me a shortened version of the text?

At my school I usually arrive at 7:30am, so no one else is really there yet.  Except myself and usually this one other older man who tries to talk to me every morning.  Every morning I'm trying to be as unpleasant as possible so this guy will leave me alone, but he never gets the hint that I don't want to talk to him, ever.

Now you probably think I'm a huge asshole, but the reason I don't want to talk to him is about 10 years ago he had an affair with my mother.  Cheated on his wife with my mom, strung my mom along promising he was going to get a divorce, but in the end he dumped her and she cried for weeks.  I think she was really in love with this guy, and he used her up and tossed her away.  

He doesn't recognize me, for one it was 10 years ago and I'm 23 now, for another I have a beard that pretty adequately conceals my facial features.
<bot>: Guy who broke my mother's heart 10 years ago doesn't recognize me, spends a few minutes nearly every morning trying to talk to me while I give him the cold shoulder.
