My friend David sent me this line by A. E. Housman. Can it be true?

"Experience has taught me, when I am shaving of a morning, to keep watch over my thoughts, because, if a line of poetry strays into my memory, my skin bristles so that the razor ceases to act."

Taking chickens to the slaughterhouse this morning, then going to my son's piano recital. There's variety for you.
