Mistakes, Repentence, Direction

A police officer pulls over an eighty-six-year-old woman because her hand signals were confusing. "First you put your hand up, like you're turning right, then you wave your hand up and down, then you turn left," said the officer.

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

"Then why the up and down motion with your hands?" asks the officer.

"I was erasing."
