HAVE YOU EVER BEEN GUILTY OF LOOKING AT OTHERS YOUR OWN AGE AND THINKING...SURELY I CAN'T LOOK THAT OLD? WELL, YOU'LL LOVE THIS ONE.
MY NAME IS PATRICIA, AND I WAS SITTING IN THE WAITING ROOM FOR MY FIRST APPOINTMENT WITH A NEW DENTIST.
I NOTICED HIS DDS DIPLOMA ON THE WALL, WHICH LISTED HIS FULL NAME. SUDDENLY, I REMEMBERED A TALL, HANDSOME, DARK-HAIRED BOY WITH THE SAME NAME HAD BEEN IN MY HIGH SCHOOL CLASS SOME 30-ODD YEARS AGO. COULD HE BE THE SAME GUY THAT I HAD A SECRET CRUSH ON, WAY BACK THEN?
UPON SEEING HIM, HOWEVER, I QUICKLY DISCARDED ANY SUCH THOUGHT. THIS BALDING, GRAY-HAIRED MAN WITH THE DEEPLY-LINED FACE WAS WAY TOO OLD TO HAVE BEEN MY CLASSMATE.
AFTER HE EXAMINED MY TEETH, I ASKED HIM IF HE HAD ATTENDED MORGAN PARK HIGH SCHOOL .
'YES. YES, I DID. I'M A MUSTANG!' HE GLEAMED WITH PRIDE.
WHEN DID YOU GRADUATE?' I ASKED.
HE ANSWERED, 'IN 1975. WHY DO YOU ASK?'

One perceives others to be old but never themselves. It is the young spirit in the old body syndrome.
Went to the eye surgeon to be measured for a cataract just today and I said to my wife that, "We were surrounded by old people, surely I am not that old?" But she gave the real dose of reality.
YOU WERE IN MY CLASS!' I EXCLAIMED.
HE LOOKED AT ME CLOSELY.
THEN...THAT UGLY,
OLD,
BALDING,
WRINKLED FACED,
FAT-ASSED,
GRAY-HAIRED,
DECREPIT
OLD FART 
ASKED...
"WHAT DID YOU TEACH?"
