Could you find an airtight bin to put them in horizontally, then slide under the bed? Save a bag of your butt droppings to toss around the room to cover the smell.
Did you just say "save a bag of your shit to throw around the room"? LOL WHAT? I'm sure that would just make him investigate more!
I smell shit, why do I smell shit in a bedroom? Do you have a dog? Because I smell shit!
Btw for smell go get some ona pro block punch some holes in the lid and let it sit in the room 4 days before he comes.. then the day he gives notice move the ona into the living room..
