Work and dead batteries

Good news: I'm going back to work tomorrow.

Bad news: The battery problems that I noticed when I ran out to get a new monitor on Monday have apparently worsened to the point that my car will now not start. I spent much of these past few days running errands with my mom in her car, so I didn't actually get to check the car until now. Looks like I'll be borrowing her car again for these next four days, and then spending money on a new battery next week. Dammit.

The original battery lasted over eight years; this one isn't quite four-and-a-half years old.

I hope it's just the battery.
