You have left something behind, quite carelessly. I locked it in your old abandoned room, because that room smells of you (pine trees, heather), and I would think that this thing you left behind would be calmed by that. It just thrashes around, emitting a high-pitched screech at the edge of my hearing, like something blurring in and out of focus. Why did you leave this behind, so carelessly? It even looks like you. You should have taken it with you. I’m sleeping in the treehouse tonight. You have a key. I expect this thing to be gone by morning.
