“Hey Steve Davies, I trust your well.”

This is the start of an e mail I got from somebody I hadn’t spoken to in a while. I was puzzled and figured that he meant he would buy water from me if he was passing through a drought zone in the desert or something. A nice compliment, but I don’t own a well. Then I realized in a flash of clarity that he must be enquiring about my health.

Ah, the power of punctuation.
