Hmmm. . .

I’ve run across this in the past and just recently came read it again in an Education World Weekly Newsletter issue:

Driving her car one afternoon, Miss Simon, a high school English teacher, rolled through a stop sign at a most inopportune time. The flashing lights that appeared in the rearview mirror meant only one thing.

As the police officer stepped up to the teacher's car window, they recognized each other immediately. Of course, the officer was one of Miss Simon's former students. He couldn't control his pleasure at seeing his former teacher, or giving her a piece of advice…

"Miss Simon," the officer said, "those stop signs are periods, not commas."
