Who needs a hearing aide?

A man feared his wife was not hearing as well as she used to, and he thought she might need a hearing aid. Not quite sure how to approach her, he called the family doctor to discuss the problem.
The doctor told him there is a simple informal test the husband could perform to give the doctor a better idea about her hearing loss.
"Here's what you do," said the doctor. "Stand about 40 feet away from her and in a normal conversational speaking tone see if she hears you.
If not, go to 30 feet, then 20 feet, and so on until you get a response."
That evening, the wife is in the kitchen cooking dinner, and he was in the den.
He says to himself, "I'm about 40 feet away. Let's see what happens." In a normal tone he asks,
"Honey, what's for dinner?"
