Body Language

Body language. The way we walk, poses as we talk, hand gestures, eye contact or avoidance.
More armor against the world.
Survival modes. Survival codes.
I have an anti theory. People who act tough, are not. People who come across as know it alls, know nothing. People who try to impress, are unimpressive. People who try to intimidate, are cowards.
Don't accept surface impressions. Don't take anyone seriously.
Especially yourself.
