Our house faces the end of a street. Our mailbox is a brick column with two boxes. One for us, and one for our next door neighbor.

Frequently, when I go to get the mail, the doors of the mail box appears dented as if someone took a baseball bat to them. I've even seen my neighbor's box with the door just hanging off the hinge about to come loose.

This week, the entire brick column is now pulling up out of the ground and leaned backwards. It isn't loose at all if you push on it. It looks like a car crashed into it and partially knocked it over.

We never hear a noise of a car crashing into our mail box, and never hear roudy kids outside...

Why does our mailbox keep getting beat up? Any ideas? Could it be the mail truck?
