“Nasrudin,” a friend said one day, “I’m moving to another village. Can I have your ring? That way, I will remember you every time I look at it?”

“Well,” replied Nasrudin, “you might lose the ring and then forget about me. How about I don’t give you a ring in the first place—that way, every time that you look at your finger and don’t see a ring, you’ll definitely remember me.”
