A concerned husband went to a doctor to talk about his wife. He says to the
 doctor, "Doctor, I think my wife is deaf because she never hears me the
 first time and always asks me to repeat things." "Well," the doctor
 replied, "go home and tonight stand about 15 feet from her and say
 something to her. If she doesn't reply move about 5 feet close and say it
 again. Keep doing this so that we'll get an idea about the severity of her
 deafness".

 Sure enough, the husband goes home and does exactly as instructed. He
 starts off about 15 feet from his wife in the kitchen as she is chopping
 some vegetables and says, "Honey, what's for dinner?" He hears no response.
 He moves about 5 feet closer and asks again. No reply. He moves 5 feet
 closer. Still no reply. He gets fed up and moves right behind her, about
 an inch away, and asks again, "Honey, what's for dinner?"

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