I agree -- weather had nothing to do with her wanting to start the car, although it may have been a good excuse when it was cold outside. Even though she was told not to do it and it wasn't cold outside that day, I think she started the car as many of us would have done at that age. We were trying our best to be "older," and a big part of that is driving. In NC, you have to be 16 to have a regular driver's license, but at 13, in Hania's mind, IMO, 13 is not too soon to start thinking about it. I remember asking if I could back the car out of the garage before my mom and I went out, etc.
I think that was all there was to what she did.
