An elderly lady was concerned about her husband's hearing. It seemed that every time she would call him, he wouldn't respond.
The lady went to the doctor to ask his advice. The doctor said to her, "when you go home, tell your husband to stand at the end of the hallway, and you should stand at the other end. Ask him what he wants for dinner. Continue to move him closer towards you until he responds to your question so you know exactly how far away he is from you when he finally hears you."
She thought this was a great idea. When she got home, she placed her husband at the end of the hallway and yelled, "Herbert, what do you want for dinner?"
There was no response. She moved 10 feet closer. Again she yelled, "Herbert, what do you want for dinner?" No response.
She moved another 15 feet closer to where she was now practically face to face with her husband. She yelled even louder this time, "HERBERT, what do you want for dinner?!!"
Herbert yells back at her, "For the THIRD time, I want chicken!!"
