I flipped at first, thinking the foam was from the cushion. It wasn't. It was from a dangerous slipper that didn't survive. It will never threaten the world again. I asked Jack about it.
He has no idea how it happened. He didn't see a thing. He's not a great guard dog. He somehow slept through an intruder coming in and chewing up my slipper.
What? You think Jack did it? Have you seen this face? Impossible.
