I'm going to kick a girl out of my car and leave her on the side of the road
Why do you want to kick her out of the car?
She did not feel comfortable in the back of my car for some reason.
Maybe you should just let her sit in the front. It is wrong to just leave someone stranded on the side of the road.
I know, but she wouldn't stop complaining. What else was I to do?
I would have told her to stop complaining, or have her sit with you in the front. Why was that so hard, she could die on the side of the road or someone with bad intentions could pick her up? Politeness goes a long way even in this day and age, I always use it myself.
