Addendum
So in my last post I threw out a quick little one liner about how our youngest heard the Alanis Morissette line "I'm brave but I'm chickshit" and asked me what a chickenship was. Funny. What I left out was the rest of the conversation, where I was explaining to her what "brave" meant. I said something to the effect of "when you're scared to do something, but you do it anyway, that's brave."
She said, "If my sister was in a cave with a bear, I'd go in and kill the bear and save her."
Because they fight so much, I sometimes forget how ferocious their loyalty is to each other.
Before they came to our home, they had to live with so much chaos. I'm guessing there were many times when each other was all they had.
