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.

I certainly hope you'll forget about me. It's unhealthy to nurse grudges against random, online commenters.

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