oh and regarding bird-flipping: a pet peeve I have (bird-flipping would be one too, though I haven't come across much of that) is women our age proudly posing with cigarettes. I mean, if you are still smoking at this age, why are you flaunting it? I am saying this as someone who occasionally will sneak a cigarette from the side of the house from time to time.
That, and people posing with artillery while making aggressive facial expressions. INTIMIDATING *snort*
