Do you ever get the urge to act like a bit of a jerk in public?
I'm not talking about pure cruelty here, mind. I'm thinking more along the lines of knocking over an intricate row of dominoes while someone is carefully lining them up, or flicking the base of a house of cards just as the final one is about to be put into place. You'd never actually do something like that of course, but that little devil on your shoulder sure would like to see it happen...
How about wandering into a house party, downing a bottle of champagne in one go and then roaring as you smash the glass bottle against a wall? That kind of swagger is probably acceptable for high profile rock stars and over-the-top characters in raunchy teen comedies but for your normal everyday person? I don't think they could get away with it.
