Keeping me grounded

You CAN, on rare occasions, have a conversation with a 4 year old. I have and felt very rewarded for doing so. We connect, we bond, we share thoughts. Then there are times like today when we are having a conversation and I am handling my end well and the retort I get back from my daughter is "Daddy, poo and tinkle live under ground". Hmmmm....really sweetie, well....Daddy didn't know that. Point well taken. I beleive I shall use this phrase or another gem of hers when I am stuck without an answer at work. "Why wasn't this taken care of yesterday?", and I shall reply "My big girl pants are up my bum-bum". They can't fire you if you're crazy,..really, I looked it up.
