Yeah, you got a lot of problems. I seem to have a knack for married women about twice my age. The young single ones wont touch me or even carry on a conversation.
I use to get a lot of calls to dispute insurance charges at the bank. Someones child would come home, finish or quit school and the parents got a new charge on the bank account from the insurance company. They took it upon themselves to charge extra as the child is home even if the child has their own car and own insurance. The insurance company assumes the child will drive the parents car.
When my senior mother moved in with me I got a discount and she quit driving in the 90s.
I wouldnt worry too much about the "cheap" battery. Its more than likely a lower capacity as they are almost all made in the same factor with different stickers. I try to get the biggest I can fit and afford myself.
