I was unaware brushing teeth was a contact sport

I don't know what is going on with JC & HT these days. I do not remember JR and JC going through a phase like this, but perhaps I (my sanity) have blocked it from my mind like so many other unpleasant things in life. I honestly didn't know it was even possible to fight over some of the things that they fight over. Tonight for instance, they managed to come to blows while brushing their teeth. I can't imagine what they could possibly have been fighting over...we have two sinks for goodness sake!
