A 2 year old's definition of gravity

The other day I asked Hannah if she remembered what gravity was. She said gravity makes the ball come back down, and then she went on to tell me it makes her shirt go up. I was confused by this so I asked her some more questions to see what she was talking about. She explained to me that when she turns upside down, gravity makes her shirt go up. Brian and I were amazed since we never explained this to her. I guess she really does understand gravity!
