I was watching my daughter in pretend mode when she didn't know it (so don't talk to her about this instance or she'll know I was). Anyway, she was doing a trick and turning sideways as if asking a friend.
"Can you do that?"
Then being the friend she tried it.
She did this back and forth many times until finally the so called friend couldn't do it. To that she replied, "See, only I can do it. " Big smile.
My son meanwhile is making very interesting noises as he is playing in the imagination with his blanket wrapped around the neck and fighting movements.
Oh, to be young and in pretend world again.
