Judge

have you ever look at a person,

judging him/her only by their body language, facial expression, posture, non verbal communication and you directly made an assumption out of it?

and then you got shocked, when that person starts speaking and every judgment you ever had is invalid.

so why not before avoiding someone because they were thought as ego or unapproachable, but instead go and say hey , who knows that person will be your true friend or someone you once desired?
