SCENE: New Year's Eve day. Outside a busy liquor store, a teenaged male oh-so-casually asks various passersby to help him buy some booze. Upon being turned down by a rough-around-the-edges middle-aged guy, the following exchange erupts:
Teenager (bitterly): Why is it only old people are allowed to buy beer? Middle-aged guy (more bitterly): Because we're the ones who NEED it.
