I pulled my mattress out of the closet (yes, the closet it that big!) and put it in the middle of the room, away from the walls (worried about wet paint), and it was silent! I could not hear all the normal stuff outside. I don't know if it's because the bed was lower (no box springs or anything till the paint is fully dry) or because I was away form the walls (less sound reflects?), but it was eerie quiet! If the bed wasn't in such an awkward place, I might leave it that way.
So this means all my excuses for procrastinating on moving all my stuff in are gone. But it also means I need to have a true house weirding soon. I'll probably make the place all trippy for that, but I won't leave it that way this time around. I'm hoping for a simple clean look for the place. Unlike the psychodelic bear den that Casa de Cesspool was.
