Hearing Problems

oldmanEthel thinks her husband is starting to go deaf so she decides to test her theory. She stands about 30 feet way and calls to her husband, “Marvin!”
There was no response.
She then stands 20 feet away and calls out to him again, “Hey Marvin!”
She is surprised that he still doesn’t hear her call.
Ethel tries again, and this time from 10 feet away, “Marvin!”
Marvin turns around and says, “And for the 3rd time Ethel, what do you want!?”
