Where does the rain come from?

Jerry, who handles our rat population, told me that on some days the rats will eat the poison and on others they will not. Jerry knows everything about controlling pests and probably should be given a Ph.D. in the subject. I asked him why the rats are such inconsistent eaters. I was shocked when he said, “I don't know.”

I went out in the rain, befuddled by this apparently simple koan that any three-year-old can answer (it sadly turned out that my two three-year-olds were, unfortunately, way beyond their ages).

Out in the rain, I couldn't tell where the rain was coming from—but I could feel that I was getting wet.
