There are so many, but here's the foremost
  1. My son's PSP; he was getting bad grades, so I hid the thing. Still lost after 4+ years
  2. The key to my hope chest; fortunately, the hinges tore off the top, so I guess I still have hope.
  3. The goddamn charger for my Bluetooth headphones
  4. The goddamn charger for my iPad
  5. An emerald ring given to me by my first husband (unless he pawned it)
  6. My first guitar, all my sheet music, and an aquarium because I left my hatchback VW unlocked when I was moving into our 1st apartment and had to have sex before we unloaded the car.
