Whenever my wife comes in and out of my car, I have to remind her not to slam the door. It seems like she can take out the window when she closes the door. Recently, my co-worker and I used my car to drive to the airport and he did the same thing too. When we came back from Cali yesterday, he got in and slams the door. When he got out, I reminded him to take it easy on the door. I don't think neither gets a kick out of slamming doors so which leads me to think that it's something related to the door. I haven't looked at the door or hinges yet for something that I can adjust so I come to CL first for clues.
