Yesterday I was waiting at a light behind a woman talking on a cellphone. About 5 seconds after the light turned green I was about to lean on the horn and yell
It's a car, dammit, not a $%&*$%$ phone booth! Hang up the bleeping phone and drive, bitch!
but then she finally started to move, just as I lightly beeped the horn. I just rolled my eyes as my blood pressure returned to a more normal level. I once saw a bumper sticker with that sentiment, and it just pops into my head whenever I see someone driving and yakking.
