When You Have His World. Content Warning.
When you have his world, it will be dark in there for a moment, but clean it out with a Swiffer and some Febreeze. Make it smell clean. Commercially clean. Open the windows to air it all out. A pigeon might fly in, and for a moment you might be afraid it will shit on the carpet, but nothing bad will happen. Guide the pigeon to the window with a feather duster, and it'll fly away into the sky.
