1st grade wisdom

Tonite as the kids were cleaning up and getting ready for bed; Ian said he had to go pee. Connor pipes up and says "You mean you need to empty your bladder?". They are learning about the human body right now. They have cut their bodies out and they are plastered on the walls in the hallway. They keep adding different parts like the heart, lungs, brain and of course the bladder. That Connor is a walking book of information. What am I going to do when he is ahead of both Ian & Kolette and he learns much more interesting info in health class??????
