Tonight, we realize, is your night to forget all . . . before tomorrow's plotting of the year ahead (or lamenting the one that passed). . . . But before the hats and horns take over, here is a synopsis of some of the information we've passed on to you in 1980, the stuff of your daily lives that we found most significantly struck a chord. And so we don't sound completely presumptuous, we will say you've asked for it. So clip away. . . . There could be something here for you to add riches, or enrichment; to deal with loneliness, or aloneness; to enhance your physical health, or mental; to build a family, or not; to take charge in an old job, or change to a new; to stretch your muscles, or unwind; to insulate your house, or to just have fun . . . in '81.
