I lose everything that can be held in my hand at one point or another. I lost a complete set of keys with a watch that was given to me by a dear friend-a PTCruiser watchfob that didn't even work anymore, but I still cherished it. The keys also had my classroom passkey for the school I worked in, so they weren't real thrilled. I went to all the stores in the shopping center I was pretty sure I lost them at, but no dice. I think someone found them and just took them for the watch.
I never did tell him I lost it.
