But who are you?
One day, a man came up Nasrudin, and they began to discuss a variety of matters, including local gossip, personal issues, their families, businesses, and philosophy topics.
After about one hour, the man said, “I must go now.”
“Excuse me friend,” replied Nasrudin, “but who are you?”
“What do you mean? You want to tell me that you don’t know who I am?”
“Then why have you been talking to me for one hour on all sorts of personal matters?”
“Well, I saw your clothes, beard, and turban, and I mistook you for someone else.”
