A couple of years ago, Dad was having problems with his blood pressure and was worried about it. Every time he noticed something abnormal, he would think it was because of his blood pressure.
One day, he came home and noticed a blue line on his forehead that looked like a vein and told his wife Grace that he thought something was terribly wrong and he needed to go to the emergency room.
They went to the hospital and they immediately pulled him back into a room and started checking to make sure nothing serious was going on. Once all their tests had been completed and they were unable to find out what was wrong, they admitted him for further tests.
A young doctor came into his room (an intern) and looked at his forehead and said he had never seen anything like that and he was going to have to wait for the attending physician to look at it.
A few minutes later, another doctor came in and looked at his forehead and said "I think I may know what this is". Dad said, "what... what is it".
The doctor reached over and grabbed some gause and soaked it with some alcohol then wiped Dad's forehead, at which point the blue line dis-appeared. Grace looked on in amazement as Dad asked "what, what happened". When the doctor said he had wiped it from his head, it suddenly dawned on Dad what had happened.
He had gone to wash the car that day, and apparently some of the soap from the car wash dripped onto Dad's forehead. Dad swore it wasn't anything like that because he was unable to wipe it off when he first noticed it.
When they went to the hospital, Grace called me (his son) and told me that she thought something really bad was happening with Dad. I was naturally concerned and told her to call me back as soon as they found out what was happening. She later called me and it sounded like she was crying. Needless to say, I was concerned .....
until I realized she was actually laughing so hard she could barely talk.
