There are also Froggys and Mouseys.
One of my favorite moments was in the middle of one of their 'arguments', Elizabeth put her hands on her hips and looked him in the eye and told him, "Don't argue with a three year old!" Of course Mr Boots retorted, also with his hands on his hips, "Don't argue with a fifteen year old!" It is all in good fun and neither one ever gets upset, they are just playing.
Elizabeth did come out on top one time. I am not sure where or how she came up with this... Mr. Boots HATES bodily secretions! He is very careful about washing hands, using clean silverware, etc. One night I came in to tell him good night. He sleeps on the top bunk and Elizabeth came with me and climbed up the ladder so she could also tell him good night. She then told him in a little girl whispery teasing voice as he snuggled under his covers, "Mr. Boots, I licked your pillow". He quickly flipped it over. She then quietly told him, "Both sides!" At which point we all burst out laughing. He laughingly told her just how gross that really was as he often drooled in his sleep.
I am not sure if she really did lick his pillow or not, but just the fact that she came up with it made me chuckle. Little sisters are really good for big brothers. I miss her baby talk already.
