Mary the deaf

An old man goes to see the family doctor, and explains:

> Doc, my wife Mary is getting deaf but she refuses to admit it and have any treatment. What can I do?

> Well, it's difficult to know the cause if she won't come, but we can try something: try to call her name from a certain distance, and then get closer calling her until she answers back. This way we can know how bad is it, and if it's getting worse.

So he comes back home and from the front door he starts calling her:

> MAAaaaarryyyyyyy

But nothing. He then goes to the kitchen's door, where his wife is, and shouts:

> Maaaaaaaaaaaaaaaaaryyyyyyyyyyyyyyy

Nothing. So he then stands just behind her, and starts yelling like crazy:

> Maaaaaaaaaaaaaaaaaaaaryyyyyyyyyyyyyyy

She turns and says

> For the third time: what the heck do you want!!!!!!!
