Borrowing a Cow

A man once wanted to borrow a cow from a wealthy man, so he had his servant send a note to the wealthy man. The rich man, who was entertaining some guests, took the note and ashamed to be taken as an illiterate, pretended to be able to read it. When reading it he nodded his head repeatedly.

"I know," the rich man said to the messenger, "I'll go myself in a moment."
