Unclaimed Property

Via a process I do not entirely understand, I have just received $70.90 from the Stanford Bookstore, by way of the State of California. If you go to the California State Controller's website you can search for "unclaimed property." Somehow, a few months ago someone (it was either my dad or my aunt) discovered that I was owed money by the Stanford Bookstore and it was listed there. Unfortunately, their database is bizarre enough that once you've looked something up there, it disappears and you can never find it again. Luckily though, they got the ID number before it disappeared, so I filled out some confusing forms, added a copy of my old student ID card, and cast them out to the government, never expecting to see them again. After just enough time for me to forget about it entirely, I received a check from the state treasury for the full amount. I still don't have a clue why this money was supposed to be mine, or why it got shuffled off to unclaimed property. I'm not going to make much of a fuss about it, though.
