I will never understand how some people can be so void of consideration. I once had a neighbor who regularly slammed her front door--very hard. We lived in the same building, but she lived downstairs and sometimes it seemed as if her slamming was going to shake the building down.
I don't know if the problem was that her door was hard to close or what, but it got so frequent at one time that I had to call management about it. After that, it didn't happen as frequently anymore, but every now and then she would start it up again. Every time she used to slam her door, it sounded like she was mad at someone or something and was taking it out on that abused door.
