I mean, you could lie here day after day, if you wanted to, and think about nothing but waterbugs. Not chase waterbugs, mind you, just think about them. You could spend your whole day, every day, just wondering and pondering about waterbugs, and talking to others about waterbugs . . . and before you realized it, you'd be old. One day you'd realize that you'd never actually seen a waterbug . . . but by then you wouldn't want to, because it would spoil all your beautiful ideas.
