Basic, objective questions that people don't often think about are too often taken as snide criticisms. I once innocently asked a juggler exactly why he juggled and he almost brained me with his wooden juggling balls. He thought my question was some kind of slam.

I thought he was great juggler. I just wondered why he liked juggling rather than, say, playing tennis or watching NASCAR. Maybe it's the sort of thing that's too hard to put into words.

Gibb asks an interesting question about the psychology of song. Why *do* we sing what makes no obvious sense? We don't speak it unless we're very drunk or something, and we worry when we hear other speaking incoherently. Singing is different.

I gave one possible answer a few hours ago. Seriously.
