<human>: I left her car lights on after taking her car out yesterday for a quick run to the pharmacy for lube. Her battery was dead. I apologized.  I called my friends and she called hers and eventually her friend came over to jump her car. I was down there with the car to help her with stuff. She connected the cables and I put the car in neutral by disabling the shift lock and pushed it to a good position in the parking lot for us to jump it. 

So the cars are connected and they're jumping and we are just sitting in the friend's car. She wants her friend to jump her car for 10 minutes. I have a test tomorrow morning, and she knows about it. I also work from home, and she knows that. So I told them I'd go upstairs and do some work/studying.

I come down 10 minutes later to check the progress. I help her push the car around again because the jump failed while she's sitting in the car. I ask her to come help and it finally starts rolling up the hill. She's like "it's not that hard" and I'm like "why don't you do it by yourself?" Then she goes on a tirade about how I'm being rude by going back upstairs and not helping her? 

Excuse me? I was the one who figured how to shift the car from park to neutral so the jumper cables could even reach the car. I pushed your car around in the parking lot. I was out there for every step except when the actual jump was in progress and there wasn't anything for me to do but sit in the backseat of an air-conditioned car when I could be upstairs doing work or studying. I calmly told her all this and she's just like "you don't get it." What am I supposed to do in the back seat of a car? She could easily text me to come out and help if there was anything else to do. Yes, I know I ran down your car battery, but I apologized, and I helped you jump your car (albeit unsuccessfully).

Can you condense the text into a few key points?
<bot>: Helped my gf jump her car; snapped at her once and she thinks I was being rude throughout. What am I not getting?
