Something about me

Just realised something about me after a little thought about it.

1) i like to talk to people who are quiet, but i got nothing much to talk to people who talks alot
2) i tend to walk with people left behind of a group than those who are walking infront
3) i like to be with a small group than going to a big party
4) i am a very calm person, i can swallow most of the nasty thing to me.
5) i dun haf much emotions.

what am i..
