this guy... ( something spinning on my mind since yesterday )

he was walking down the room, looked like tried to find something or someone..and finally he saw me. i was waving my hand, then he came. When he walked, there was something spinning in my mind. I think about this " God.., this guy is nice, but there's something inside of him that make me 'ill feel' a.k.a. ilang feeling and maybe some of the girls will think the same thing". how couldn't say that, he still act like a man that have just graduated from high scholl.. Helloww.., you are more than 20 and our age is almost same.., how can you act like a young boy..., you're a growing up man, and you have to know..!!! Man, you supposed to be live and life as a real man. Actually he's not so bad, nice, and i still can't get the reason why he hasn't a girl yet.. he's my friend, i fell nothing with him even try to flirt on him.. no no no..it's a big NO. Just my little curiosity.
