Walked out to my car this morning, ready for work. Sit down, set up my iPod, turn on the car. Ummm. Let's try that again. Turn on the car. Turn. On. The. Car. Nope. Not happening. Apparently, my car was angry that it was left alone for a few days and decided to kill the battery. How? I do not know.
So, lesson learned. My car has an attitude and I need to be more sensitive to it's needs apparently.
