I have a Friend...

I have a friend, he is quite cool, he made me upset sometimes... All because of he doesn't seems like wanna be a very good friend with me.
Actually I really hope to become one of his best friend. He is a very kind man, humble and sometimes quite funny. But after that conflict caused among us, he looks like totally disappointed on me. I've sad for whole holiday (Nov- Dec) everyday blame myself why am I so stupid go and play that game with him.
After holiday we went back to school, I still same class with him. He still the same... never smile on me and like I'm transparent. Seeing him chat with other friends, his laugh, his smile make me missed last time before the conflict happened... It quite suffer huh...
I know the problem was on me, I don't dare go and have a chat with him... Scaring of he do not reply me...
Finally, I started my first conversation with him in Facebook... After a couple week, I start Msn him and now we're good back already... I still feel guilty... And now I can't find any topic to chat with him... I just can follow what he do and try find some topic to chat... I'm so stupid huh? I feel that way so... So what can I do now? In real life we cant chat... But when he online in Msn/Facebook/Blogspot, I can chat with him...
Maybe it is just what I think and actually the truth is not as bad as I though... =.=
