nature of a man

Like the saying goes "A man is known by the company he keeps". If he is good he has good friends. If he is bad he has bad friends. Then follow his deeds and actions. If he is a shy and introvert person by nature he does not have much friends. Whereas an extrovert goes out of the way to make friends. So i feel a man's nature can be assessed with the friends he has. Happy mylotting.
