Old age

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 ALICE SMITH AND I WAS SITTING IN THE WAITING ROOM FOR MY FIRST APPOINTMENT WITH A NEW DENTIST. I NOTICED HIS DDS DIPLOMA, WHICH BORE 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?' 'YOU WERE IN MY CLASS!', I EXCLAIMED. HE LOOKED AT ME CLOSELY. THEN, THAT UGLY, OLD, BALD, WRINKLED, FAT ASS, GRAY-HAIRED, DECREPIT SON-OF-A-BITCH ASKED, 'WHAT DID YOU TEACH ???'
