After putting the kids in bed, I went downstairs to put a load of diapers in the dryer, and snatch up the last piece of my birthday cake. As I was coming back upstairs, I saw Oliver coming out of the bedroom, and our conversation went something like this:
Me: Oliver, what are you doing out of bed?
Oliver (holding up his right pointer finger): Because I put my finger in my butt
Me: You what?
Oliver: I put my finger in my butt because I need to wash my finger.
Me: Just that finger? Why don't we just wash BOTH of your hands.
With that he got the stool and put it in front of the sink.
