AWWW...HOW CUTE <3 what do you think? = )?

soooo....the guy is in my cl of about 100 ppl @ college...i'm friends w/ him on facebook since september (the beginning of the semester) and never spoke to him before...his birthday was at the end of october...i gave him a cute facebook virtual gift...yesterday was my birthday and he was like 3rd to write on my wall "happy birthday...i'll see you in cl if i could wake up in time :p lol"...i was soooo surprised w/ it and was sooooo sweet of him... i would have never expected him to say anything let alone remembering what cl i was in with him...i really never said anYthing to him and he was kind enough to say something unlike other ppl i don't really know & never meet/spoke with...why did he bother? (PLUS THE FACT THAT HE WAS 3rd on my wall...& wall post #1 does not really count cause the guy is my best guy friend...so it was like he was really 2nd...awww)... although it made my day...= ) what does it really mean? i wanna know what uuuu think...
