Personal stuff...S

Warning: life issues to follow, here is the most gorgeous car in the world as payment...

Anyway. After my mother in law's husband went insane and left her, I invited her to live with us because the bank foreclosed on her house. Things have been alright for a while, and it's great that my mom doesn't have to watch my son every day now. But. Recently, my wife and and her mother have started fighting. A lot. And the gaps between are tense silences that are broken only by snide remarks. They both seem to be acting like children. I dunno what to do, because they are both in the wrong most of the time, but I feel like I should do something as the man of the house.
