My four year old informs me of this as we drive to a birthday party for his wee friend.....I asked him if he was enjoying having me to himself again and he said "yup"....followed by his deep thinking on life..."Am I five?", "No", "Are you five?" "No"......"That's why we are not at school!"...how can you argue with the logic of that? Life is sooo uncomplicated at four...wish it was that easy at 4.....tee.
