what do I even say??

I hear the kids singing at the top of their lungs in Emma's bedroom...oh, i think, they are getting along so nicely....
... then I hear screaming and yelling...
Emma runs into the kitchen crying.
I say "Whats the matter honey?"
Emma: "Benjamin will NOT let me praise the Lord and its making me so mad!"
I stare at her and have no idea what to say... this happens to me a lot :)
