I shave my head. I have to shave it every two or three days or I look like a mangy old dog. I wait until just before I go to bed to shave it, at which point I’m too tired and I tell myself I’ll do it in the morning before work, which of course I never do. So I end up shaving it once every three weeks, and spend most of the time looking like a mangy old dog.

I eventually hit upon the strategy of shaving a small patch somewhere on my head before I go to bed, which forces me to do the rest of the job in the morning before work. Except that I usually forget I did that and often go to work looking like a mangy old dog that somebody tried to shave before giving up. Fortunately I’m a school bus driver so I only scare children.
