Confusing Signals

A Florida officer pulled over an eighty-year-old teacher because her hand signals were confusing.

"First you put your hand up, like you’re turning right, then you waved your hand up and down, then you turned left," said the officer.

"I decided not to turn right," she explained.

"Then why the up and down?" asked the officer.

"Officer," she sniffed, "I was erasing!"
