This past weekend, my low-tech Dad bought himself a very high-tech satellite system. A few hours after he had it installed, I received a phone message from him on my answering machine. It went something like this: "Hello? This is your Dad. I need to borrow your axe so I can chop a hole through the ice in the lake because that's where this stupid satellite system is going." But as it turned out, he eventually figured out how the thing worked so he didn't actually need my axe after all.
