There's a story (dunno if it's true, but it could be) about an anthropologist who is living with an African tribe to study them. He gets to know the tribe and is accepted by them, and one day a village elder invites him to join a group sing that evening. The anthropologist says "No, no, I can't sing." The elder looks at him in astonishment and says, "What do you mean you can't sing? You can talk, can't you?"
