A concerned husband goes to see the family doctor: "I think my wife is deaf. She never hears me the first time I say something. In fact, I often have to repeat things over and over again."

"Well," the doctor replies, "go home tonight, stand about 15 feet from her, and say something. If she doesn't reply, move about five feet closer and say it again. Keep doing this so we can get an idea of the severity of her deafness."

Sure enough, the husband goes home, and he does exactly as instructed. He stands about 15 feet from his wife, who is standing in the kitchen, chopping some vegetables.

"Honey, what's for dinner?"

He gets no response, so he moves about five feet closer and asks again.

"Honey, what's for dinner?"

No reply.

He moves five feet closer, and still no reply.

He gets fed up and moves right behind her—about an inch away—and asks one final time, "Honey, what's for dinner?"

She replies, "For the fourth time, vegetable stew!"
