A wealthy man in town always made a big show of telling Mulla, "Please, come visit my home anytime! I'd love to host you!" One day, Mulla decided to take him up on the offer. As he walked up the street, he saw the man looking out his second-story window. But as soon as the man saw Mulla coming, he ducked out of sight. Mulla knocked on the door. The maid answered and said, "I'm sorry, the master is not home. He went out a few minutes ago." Mulla smiled. "Very well. When he returns, please give him a piece of advice from me: Next time he leaves the house, tell him not to accidentally leave his head in the window. It makes people suspicious."
