I sometimes carry Louise on my shoulders while walking the dog around the block. One day, as I was doing this, I playfully gave a little jump, bouncing her up and down. We laughed. She said to do it again. I did it again. She said to jump higher. I jumped as high as I could. She laughed and began hollering, "I am so high! I am so high!" over and over as we walked along.
I considered quieting her but decided not too. She wasn't actually bothering anyone, and I wasn't ready to give the Nancy Reagan talk to my 4 year old.
The tough kids on the corner did give us funny looks, though.
