I have the same affliction. The doors and trunk on my Accord close very easily. My family seems to like slamming them, though, and I think I know why. Our Regal and Silhouette have heavier doors and trunk lid, which require more effort to close. They are used to driving or riding in those cars and not my Accord. I ask them nicely not to slam the door or trunk when they do it and try to remember that their experience is with the older cars they normally drive or ride in.
