How do you discover a friendly person in first meeting?

Its a collection of things. The eye contact, body language, smile, frequency of touching involved, the thoughts, the words all of them combine to mak u realize if u can be friends with someone. More often than not, it happens so quickly that we are not even aware of it. Like, you wont be too friendly with someone who just stares blankly at some where else while u talk to her, neither would u be want to friends with someone who keeps gazing in your eyes as if something else is on his/her mind. SImilarly works for other things, the body language, the confidence, introverted or extroverted .. complemenrs you and your ideas or is like a twin .. I think all of them count .. I think i missed a few in fact. :P

it's really hard to judge certain person at the first sight. i used to think that people should be friendly at any time if there's no special reasons. maybe it is because the look, the smile, the speaking method. wish you happy day.
