Cell phone

When a customer left his cell phone in my store, I scrolled
through his saved numbers, stopped at "Mom" and pushed send.
His mother answered, and I told her what happened.

"Don't worry," she said, "I'll take care of it."

A few minutes later, the cell phone rang. It was "Mom."

"Martin," she said, "you left your cell phone at the con-
venience store."
