Playing with our Kids... Or, How long can *YOU* play tag?

I am writing this post for my 5-year-old son, who is a believer in science and research.   You know, except when he's determined that he wants Pluto to be a planet, so it is.  It just is, so there.The other day I picked him up from school and we had some time before I needed to make dinner.

Me: "What would you like to do, babe?"

Him: "I want to play TAG!"

Me: "Playing with you is one of my favorite things...but I do not enjoy tag.  Children love to play tag - so the next time you are playing with children, you can do that.  But, what shall WE do?"
