We were in the apartment and we saw a big car go past which looked like it was being driven by a little girl. It stopped in the field behind the apartment so I went to check it out. It turned out to be full of girls aged 8-11, and the girl driving kept saying she was 16 or 18. I asked to see her license, but she wouldn't let me see it. (she obviously didn't have one.) I put the parking brake on and went back inside. I came out a little later and they were still there, trying to get the car going. I took off the parking brake and decided to drive them myself wherever they were going. They were just going home, so I drove them there. On the way we saw a bunch of accidents and police cars driving by. I told the girls that they could have easily gotten in an accident, and to drive the point home, I told them we could've had to swerve, (as I swerved) but when I did there was an accident right in front of us and I really did have to swerve. Unfortunately, the accident took up most of the road, and I hit a truck, but not very hard. We were all fine and we kept going. We got to their house, (actually it was their brother's house, and it was huge) and I parked in the backyard. I told them to start looking for the car's registration, as I figured the police would be coming soon. After much looking, we didn't find it. One of the girls (a bigger 13 year old) tried to flirt with me but I pushed her away. The police never came, so we didn't need the registration.
