The following violates my single topic per post rule. I blame myself for not updating more diligently.
Offered to drive my sister to the station on Monday, as she'd just missed her bus. That was how we found out the car wasn't working. Bit of a worry, as I had an appointment Tuesday with my case manager.
I was sure it was not the battery, as I had driven the car just a few days after I got back and it was fine then. Plus that excursion was in the middle of the day, making it very unlikely I could have left the lights on.
