I couldn't care less about people who see one smiley face and go completely berserk. I never met you. I don't know anything about you. I will forget you in a few minutes.

Otherwise, all that building resentment will feed back into your insecurities, which will distort your sensitivity to criticism and magnify your next explosion.
