With a novel, you have the reader with you a lot longer, and you owe him a lot more. Obviously you have to have a plot - I say "obviously," although I think a lot of fiction doesn't, and nothing seems to happen. But to me, there should be something that happens, and it should be at least vaguely plausible. And because the readers are going to be with these characters for a long time, you have to get to know them and like them and want to know what happens to them.

Dave BarryThe obvious and fair solution to the housework problem is to let men do the housework for, say, the next six thousand years, to even things up. The trouble is that men, over the years, have developed an inflated notion of the importance of everything they do, so that before long they would turn housework into just as much of a charade as business is now. They would hire secretaries and buy computers and fly off to housework conferences in Bermuda, but they'd never clean anything.
