So it gets even better. After learning from my last mistake to plug the alarm clock into an outlet not controlled by the light switch, I went through the same alarm-setting procedure as before.
This time, I woke up at 6:04 on my own. No alarm. I look over at the clock, and it's on. The alarm was set for 6:00am, the clock was displaying the current time correctly, including the am/pm, and the alarm was on. So what gives?
Apparently, this clock has been a favorite playtoy of my son Hans for some time. He must have rough-housed enough with it to disturb the internal workings, or perhaps the speaker, or whatever. Anyway, it didn't go off as planned.
So the moral of the story is never to use an alarm clock your 13-month-old son has played with. Also, since I was humbled the last time, I have no need of further humility. I can stop praying that most dangerous prayer of all: the prayer for more humility. Can I sell you a bridge?
