The truth hurts

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 DENTAL DIPLOMA,  WHICH BORE HIS FULL NAME.
  SUDDENLY,  I REMEMBERED A TALL,  HANDSOME,  DARK HAIRED BOY WITH THE SAME NAME HAD BEEN IN MY SECONDARY 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 FAR TOO OLD TO HAVE BEEN MY CLASSMATE.  AFTER HE EXAMINED MY TEETH,  I ASKED HIM IF HE HAD ATTENDED MORGAN PARK SECONDARY SCHOOL . 
  
'YES, YES I DID. I'M A MORGANNER! ' HE BEAMED WITH PRIDE. 
  
  'WHEN DID YOU LEAVE TO GO TO COLLEGE?' I ASKED 
  
  HE ANSWERED, IN 1965.  WHY DO YOU ASK? 
  
 'YOU WERE IN MY CLASS!' I EXCLAIMED.
 
  HE LOOKED AT ME CLOSELY. 
  
THEN THAT UGLY, 
  
  OLD, 
  
  BALD, 
  
  WRINKLED, 
  
  FAT A*****, 
  
GREY HAIRED, 
  
  DECREPIT, 
  
  B****** ASKED.... 
 
'WHAT DID YOU TEACH?'
