So from what I've read in a few places, here, for example, kids brains do not fully develop until they're nearly 20 years old. Thank God for that.
So..here's some background. I get my oldest dressed in the morning for school. Usually I wake her up, pick out her clothes and help her get dressed. Sometimes I leave the drawers in her dresser open so that closing them doesn't wake the other kid. So a couple weeks ago, I left the two bottom drawers open, so I don't wake the other kid and we can just get moving. Remember that, I left 'em open.
So, she comes home from school that afternoon, wanting to play her Nintendo DSi, great. I say, I put it upstairs, in your room, on the floor, in front of your dresser. So she goes upstairs to grab it. About five minutes later she comes down, Mom, I can't find it. What? I know it's there, I put it there myself yesterday AND I saw it this morning. So I go up, to help her look. I walk into her room and I almost dropped a F bomb. She's standing there, with the bottom drawers of her dresser STILL OPEN. She's actually walking AROUND the open drawers "looking" for the DSi. I said ... Are you [in my brain #$#%@#!] kidding me? Did you LOOK WHERE I SAID?! She looks at me. Then sticks out a foot, and pushes a drawer closed. Voila! There is it, RIGHT WHERE I SAID.
My mind was seriously blown. How can you look in a place you cannot see? Without MOVING the things that block your view. She was walking around the open drawers. It still blows my mind now.
Thank GOD their brains are still developing.
