The Oblivious Movie Ticket Buyer... HELP!

Ok... So this may be a blessing or a curse... But I seem to be completely OBLIVIOUS to everything that happens around me. I like to think that I am not naive, but it seems like whenever something happens or someone is talking to me that I am completely ignorant to the underlying meaning... if there is one. For example, there is this totally hot guy at the movie theater. He always talks to me when I come up to get my ticket or get my food and it always seems like I get him when I am standing in line. So tonight, my little brother Dallin and I went to go see Harry Potter and the Half-Blood Prince, and of course, as always he was there. And when I go up to get my ticket, I always get flustered and I have no clue what to say. But tonight, it was odd to me. I went up and we were talking as usual and he told me that he had seen me at Walmart the other day and had tried to say hi to me but I didn't see him. But the friend I was with did. Okay... What am I supposed to think by this? I mean come on, he is the guy I buy my movie tickets from... I have never met him apart from buying my movie tickets... and he says hi to me at Walmart? Ok, yes I think he is FINE haha but what am I to do?? HELP ME!
