In an earlier blog I mentioned how perplexing I sometimes find my alarm clock in the morning. This morning was a classic example. When it went off, I awoke convinced that there was a numeric keypad on top of it where I'm supposed to key in the time that I want to get up. In actuality, all that's there is a snooze button and an off switch. I banged around on top of it for about fifteen seconds, totally nonplussed. This is the same alarm clock I've been using for (I think) over twenty years now.
