Bumping Into A High School Crush Again After 30yrs, Best Story You Will Hear

I was sitting in the waiting room for my first appointment with a new dentist. I noticed his diploma hanging on the wall.
It had his whole name on it I suddenly remembered a boy I had a big crush on in high school almost 30 years ago.
Could he be the same guy? 
That tall handsome dark haired boy?
Upon seeing him I discarded that thought as this balding man with the deeply lined face was way too old to be my classmate.
After he examined my teeth I asked him if he went to the school I went to.
Yes, he said. What year did you graduate? 
1977 he said, why do you ask?
You were in my class I said.
He looked at me closely.
Then the ugly, bald headed wrinkled bastard asked me.
what did you teach?
