Pet Peeve #1: Non-wavers

While driving if I let you in ahead of me, HAVE THE DECENCY TO WAVE. I have more important places to reach, and could get there faster if your P.O.S. wasn't in my way.

While driving if you cut me off, HAVE THE DECENCY TO WAVE. I know and you know that you have just done something rude. If you do so intentionally, I will see your wave as a hysterical sarcastic gesture; and commend you fellow road-rager, for I too, am that bitchy.
