IT WILL FOREVER BE 2 AGINST 1... AND I WOULDN'T HAVE IT ANY OTHER WAY!

Some of my favorite conversations between my girls, are the ones that I was not meant to hear.

Pyper and Elle were wrestling upstairs.  Elle comes running downstairs.

Elle:  "I'M TELLING!"

Elle:  "Mom- Pyper hurt my tooth."

Me:  "Are you bleeding?"

Elle:  "no."

Me:  "Get over it."

Elle heads back upstairs.  Both girls are still really mad at each other.

Pyper:  "What did she say?"

Elle:  "Get over it."

Pyper:  "That wasn't very nice.  I'm sorry she was mean."

I get between those two as little as possible.  They will defend each other, no matter how mad they may be.  Should I be worried?
