An old man was wondering if his wife had a hearing problem. So one day, he stood behind her 
while she was sitting in her chair. He spoke softly 
to her, "Honey, can you hear me?" 

There was no response. He moved a little closer and said again, "Honey, can you hear me?" 

Still, there was no response. Finally, he moved right behind her and said, "Honey, can you hear me?" 

She replied, "for the third time, yes!"
