Mike and his wife, though living far apart, often communicated with each other by writing letters. Unfortunately, Mike was illiterate, so he had to ask some one to write and read for him...
Yesterday, there was a letter from his wife, he asked one of his friend to read the letter as usual. The friends began to read aloud, "Private, for you only".
At that time, Mike placed his hands over his friend's ears.
"Go on reading it for me then."
His friend was confused, and asked, "Mike, what are you doing? Why did you cover my ears by your hands?"
Mike replied, "This is a private letter, and you shouldn't listen to your reading!"
