Graham, an old man, went to doctor for his hearing problem. The doctor fitted a set of hearing aids that allowed him to hear perfectly again. Graham returned to the doctor's in a month for a final check on the new equipment.
After some tests, the doctor proclaimed, "Your hearing is perfect!"
"Thank you for helping me," replied Graham.
"You're welcome," said the doctor. "Your family must be really pleased that you can hear again."
"Oh, I haven't told them yet. I just sit around and listen to the conversations I used to miss," replied Graham.
The doctor guessing the reason said, "Really?" You must just not be ready to believe it yourself that you can hear now.
Graham said, "Well, that's not it exactly, but I have changed my will three times!"
