I'm a firm believer that what goes around, comes around.
Last fall, after my son's soccer game, we found a cell phone in the grass. My husband picked it up and called the last phone number to see if he could locate its owner. After several attempts, and more than half an hour, we found the owner and returned his cell phone.
We then went to Walmart to pick up a few treats since my son scored a goal in the soccer game. While I was taking my daughter to the bathroom, I noticed a Blackberry cell phone resting on top of the toilet paper dispenser. I picked it up and took it to the service desk to see if anyone had lost a phone. No one had so I brought it out to my husband, whose phone is a Blackberry, to see if he could access the last phone number. I was afraid if we left it at Walmart the owner might never recover it unless she specifically remembered being at Walmart.
We called several phone numbers and finally talked to someone who knew the owner. Turns out the owner lived in another town, but worked in the same town as my husband. We ended up tracking down where she worked and dropping off the phone there (it was her work phone). All in all, it took us a few days to return her phone.
Last night, my husband misplaced his phone while we were swimming at the recreation center. He uses his phone for business and was worried the company couldn't reach him. Though we'd checked a few times, we decided to check once more before leaving. Someone had turned in his phone to the front desk. An employee had called a contact number on my husband's phone, which turned out to be me, so even if we hadn't stopped to ask, I would've discovered his phone had been turned in as soon as I got to our car and checked my phone messages.
