Three friends and I was driving on a highway. While we were going at least 50 miles per hour, we passed over a car. It had broken down, stopped on the side of the road. My friend slows down, and pulled behind the other car. He got out of the car immediate and before I knew it he was helping the other person push the car down the road to a spot where wasn’t so close to the passing cars. From the way they were pushing the car, it looked as if my friend was pushing them all by himself. I thought my friend help a complete stranger like this was a great thing, but I won’t forget his good nature or character.
