While waiting for my first appointment in the reception room of a new dentist, I noticed his certificate, which bore his full name. Suddenly, I remembered that a tall, handsome boy with the same name had been in my high school class some 45 years ago.

"Yes," he replied.

"When did you graduate?" I asked.

"In 1952."

"Why, you were in my class!" I exclaimed.
