I was in the kitchen, having just got off the phone with my mom, when I hear Calvin say from the bathroom, and I quote, "Mom, I just pointed my thing up and the pee came out."
To which I replied, in that absentminded way that moms can, "Oh, that's nice."
"Calvin, where did the pee go?"
"On the wall"
At which point I ran into the bathroom to see that yes indeed, when you point your thing up, the pee goes all over the wall. And all over the floor. And NOT in the toilet. So I ran to get a rag to wipe up the mess. And then I realized, well, I can mop the floor, but I don't really know how to clean pee off of a wall.
