England's West Country is known for its charming cottage- like shops. While visiting the area, my friend peered in through one window to see shelf upon shelf of interesting- looking books. So she went inside.

A woman appeared though a beaded curtain and asked, "Can I help you?"

"No, just browsing," said my friend.

"Fine," came the reply. "But so you know, around here most people knock before entering someone's home."
