Found a cell phone at the foot of my driveway on my way to work a few months back. Brought it to the office and before too long it rang and I answered and told the caller I had found it and to have the owner call me and they could pick it up. Turns out it was her mother's phone and mom lived in the neighborhood and must have dropped it when out walking.
I left the phone with our receptionist and when she picked it up, she said "tell him I said thanks" and left.

I was just a tiny bit miffed by the lack of a personal thank you. So much for good neighborhood spirit.
but ain't that America....

Maybe she didn't see the humor in my remark about using it to make two calls to Rome!
