That tricky Alphabet

I'm in the copy room waiting in line. A student walks in, he's a 5th year senior and an office aid. His job is to place the mail in the mail boxes. The boxes are alphabetized.

He is putting mail in appropriate boxes. He's slow but steady, checking the name on the box with the letter. Eventually he stops, looking around for a while, searching for a name.

"What are you looking for?"
"Fluke," he said.
I pointed to the name. He thanked me and went back to his business.

I started to remember how many times I woke this kid up in geometry. I remembered how he'd lift his head, and his eyes would be as red as red could be. I went back further, to Algebra I. Same game. I went back further, summer school...same deal!

Soon, he got stuck again. He stood there, looking, looking, not finding.

"What are you looking for?"
"Falkner."
I pointed to the name. He thanked me and went back to his job.

About five minutes pass. I'm still waiting for the copy machine. The young man is sorting mail and he gets stuck, again.

"What are you looking for?"
"Fahrenz."

I pointed to the name.
"Thanks," he said, and went back to sorting. By this time, it was ritual.

I said, "Those damn F's, get you every time don't they?"
