Never think that you've seen or heard it all.  Just when you think you have, you will look out your apartment window and suddenly see a woman lying with her back on the grass, a burning cigarette in one hand while playing with a hula hoop with the other hand.  And before you know it, a man will join her (minus the hula hoop).

Expect the unexpected.

Except if you expect the unexpected, then aren't you expecting the expected?
