Today, a beautiful thing happened. DD2 saw the opportunity to get DD3 to help her with her chores. However, she spun it into, "Don't you want to learn this life skill? I'll teach you how to do it."
So this is what I hear coming from the bathroom, "Help me Windex the mirror. Woohoo!! Isn't this fun?! Great job DD3!! You're doing great!" Laughing ensues.
There are a few things this lets me know. First is that DD2 knows her life skill well enough to teach it. Secondly, that they don't hate working. Third that they enjoy working together (most of the time), and fourth, when you train them and then let them fly, beautiful things happen.
