Picture a house stacked with stuff. Piles of paper everywhere. Unopened mail on the desk. Dirty dishes overflowing the sink. Clothes on the floor. Baskets of craft projects. Buckets of who-knows-what.
Dust motes flutter in the air. Strong odors tickle your nose. Doors stick and floorboards creak.
Your task is to write a story in which something happens to a hoarder, and your character is forced to deal with it.
Have fun with this one.
