Evening Wall Slot

I trotted down the quiet hallway and found a shallow rectangular display niche built right into the drywall! Inside sat a thick block of grey acoustic felt. A custom cubbyhole just for me! I sprinted, leaped straight off the floor tiles, and planted my feet onto the smooth wooden ledge. Then I backed up until my flat sides fit snugly against the felt liner. Thump! It gripped my plush edges like a tailored brick pocket. Settled and completely flush for the evening!
