my most recent arguement

i recently had an arguement with my friend. She drove me to a friends house knowing that I had to be home around 12 because i had to work in the morning at 7. She reassured me that i would be home on time. I even made her promise! Well finally at 11:50, I said that we should go since it would take a half an hour to get home. I was fine at the fact that i wasn't going to get home on time, as long as we left soon. Well she decides to talk, talk and keep talking. I was incredible irate. I finally told her again that we needed to leave, and then she tells me she doesn't feel good and just wants to stay there and not drive home. That means that i can't get home and i have to be at work at 7, i know that if i stay she wont want to wake up at 6 to drive back. I finally just told her that if she didn't drive me home i was going to take her keys and drive myself.Well she was upset, but she finally got up and into her car.I ended up driving home in her car.
