Their brains are mush. They are in teenage mode. And I know my son has asked me hundreds of times what's wrong. Um, I dont know, you broke the window, you made a mess on the floor I just cleaned, there is a new dent on my car....insert yours here> LOL!

Dont let it get to you, M. The more you do, the more he'll want to do it. You know, just like a child.
