John has discovered the toilet. More specifically, he has discovered that the toilet flushes.
I hear a distant flushing. Knowing that there is presently only one potty-trained Dolin in the house, I investigate.
Me: What did you flush?
Me: What is it?
Me: Tell Mama what it is.
Me: Tell Mama.
John, leaning over the now silent toilet bowl: All gont! All gont!
