well I just met this really nice guy at a play (like a theater) and he seemed reallly nice funny kind and over all a cool awesome guy. He didn't judge me or he wasn't afraid to talk to me. He seemed interested in me too. He complemented my art work when I was drawing and tried to say goodbye when I was leaving. He was really cool and we were interested in the same things like certain bands speech and debate drawing and being really random. I can't get him out of my head...

Well after a while it will fade. Did you two not exchange numbers?
Get on with your life doing things and this will just be a pleasant memory.
