I share my water with Benefactor every day. We don't really use sippy cups, and when I get a drink, I just pass it on to him. Sometimes he wanders off with the mostly empty cup. Usually when I'm too busy doing a few things at once to notice. And when he does, we end up with a wet floor.
So, Benefactor wandered off with my water Friday, and I chased after him, retrieved the cup from him, took a little sip, set the cup on the counter, and went to find the wetness to mop it up.
And I saw that the trail of water led me to the toilet.
I drank potty water.
End of story.
