I bought a box of self-improvement tapes-- "How To Handle Disappointment."
I got it home and the box was empty.
"Just because nobody complains doesn't mean all parachutes are perfect."
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 convenience store."
