Well, Matt strolled in today and mentioned that my parking lights were on. I figured it wasn't possible, since my lights go off when I turn the car off. Well, I went out to look anyway, and found out that the lights were on. Well, after playing for 5 minutes in the dark, and attempting to find a fuse to pull, I went back to my office and called the Subaru service dept. The nice guy I talked to mentioned that I probably flipped the parking light switch on top of the steering column. I went out and checked, and sure enough I had. I knew the switch was there, but for some reason, it never occurred to me that I could have flipped it (which I did while resetting my trip meter this morning). Anyway, it is good to know my car isn't broken, but bad to know that I wasn't smart enough to realize I am the one who 'broke it'.
Maybe the rest of the day will get better... maybe.
