A happy-ending story with a message from Mary Baker of Vienna:

Mary bought two pairs of gardening gloves the other day in the Post Exchange at Arlington's Henderson Hall. She took out her wallet to pay, and set it down on the checkout counter. But after the sale was rung up, Mary left it there.

"Just forgot," she says. "One of those things."

Mary's wallet contained the usuals: a few credit cards, a $10 bill, a bunch of miscellaneous papers and receipts. But it also contained the kind of identification that is increasingly unusual: a hospital benefits card bearing her home phone number.

Because of the phone number, Donald Hartman, the clerk in the sporting goods section of the PX, was able to track Mary down in a matter of minutes. Less than four hours after she had left her wallet behind, Mary had been reunited with it.

Take a look in your wallet right now. Anything in there with your phone number on it? There should be.

Remember: it may be too much trouble for even a well-meaning discoverer of your wallet to track you down through your address. But a phone call rests much more firmly in the category labeled "It's the Least I Can Do."
