If you don't have children yet, or have only girls, you may not want to read this post. Really.
If however, you have one or more boys, share a knowing laugh with me as I recount the following conversation I had with my three year old today:
J: Mom, what's my bottom do?"
Me: "It goes poop" (I told you not to read this if you don't have boys!)
J: "What's poop do?"
Me: "It goes in the toilet."
J: "What's the toilet do?"
Me: "It flushes."
J: "Then what's it do?"
Me: "It goes down to the sewer." (I'm no toilet expert!)
J: "What's the sewer do?"
At this point I was at a loss of knowledge about the waterworks system and what exactly the sewer doos, so I just moved my hands in a back and forth/swishing motion and said, "It doos this..." This seemed to satisfy him and off to nap he went.
