This thread touches me deeply, because the same happened to me all the time
On top of that my little car had a weight capacity of 700 lbs, and often there were 1000 lbs of people in my car.
A few times, they closed the door with their hip, to shut it tight, and yes they dented the door. That happened a few times.
Kids puting their fingers on the windows, then pushing their feet with their boots on into the drivers seat, and I could feel it, while I was driving.
And when the day was over, they would say, "are you going out in the FS tomorrow brother"?
