Why do plumbing problems show up at night?

I have great respect for plumbers, but I still try to fix things on my own. That is where I am foolish. But one problem I have is that plumbing problems seem to show up at night for me. My nemesis, the upstairs toilet, wouldn’t shut off the other night. I fixed it temporarily and got back to it on the weekend, but it clogged itself up last night. I was taking care of some BUSINESS before I went to sleep and I thought it would overflow. I still had to scramble to find the plunger and then use the plunger on an already occupied toilet bowl. Ick, ick, ick.

I remember finding most of the water pipe leaks in the basement at night, and the bathtub drain finally completely clogged up when I was taking a shower just before I went to bed, after going to the gym. Like Earl (my buddy Greg’s brother-in-law) says, “It’ll never happen when your bonus check comes in. You might as well fix it now.”
