if the mouse was a pet, it might have slept on beds? i dunno. mice are smart animals, and they apparently have long memories. if i'm right, the mouse seems to be crawling up in bed with me when i'm sleeping and leaving me items it thinks belong in a nest, like leaves and insulation, apparently as some kind of gift.

it's easier to want to kill them when they're making you sick, and if this is the source, i have to kill it. but i also want to understand this.
