Ain't that the truth. I once got the giggles in a crowded movie theatre during Michael Keaton's death scene in My Life. After getting angry because someone's beeper was going off, I realized it was mine, totally muffled, inside my purse. I had to get up & leave I was laughing so hard.
yanno. but not just in the fast food type of perspective.. even in the supermarket, many of the healthy options costs way more than the less good ones. and you can't win, because if you chose to buy only the healthiest food, then you would have to stop buying other things, like say.. a roof over your family's head.
