Beginning of the holidays and amazingly life manages to become more, not less, hectic. Anyway, a recent nugget of news from a Swedish paper is worth a break: One car in three reported stolen during December is actually not stolen at all (in Swedish).
People forget where they parked, or they mistakenly think they took the car when they didn't, and when they can't find their car they report it stolen. This happens throughout the year, but is especially common during christmas season. Large parking lots, lots of identical-looking cars, and the stress of the upcoming holidays all contribute. I'm not immune myself; I've thought my bicycle has been stolen more than once when I simply couldn't remember where I parked it.
