Summer vacation gives you plenty of time to think about the deep mysteries of life.
At lunch today:
Miss Dog Lover (chafing at directions for how to dress for a youth group function tonight, having decided her knees are ugly and she should not let them show), "Why do people have to have knees, anyway?"
Mr Music (replying because we all know that with Miss Dog Lover there is no such thing as a rhetorical question and she will not let go of it till satisfied), "Because if we didn't our knees wouldn't bend and they'd stick straight out when you sat down."
Miss Dance, "And you would have to walk like this." (demonstration)
Apparently these explanations sufficed. Miss Dog Lover is now dressed appropriately, and yes, her knees are showing.
If we didn't have knees - we'd have the problems Barbie does in getting in and out of our fancy pink sports cars. A giant hand will have to come and pull us out by our torsos. And we'll just hope our feet don't get stuck on the steering wheel.
