It was just green carpet, but he couldn't remember that far back. Couldn't recall much, after his wife kicked him out (what'd she mean he was odd? What was odd was forgetting to wash your hands after going to the toilet, or touching the cat and then touching your mouth...). He had no clear memory of arriving at the hostel--only that when he awoke, he put his feet down on damp, musty-smelling green fuzz.
Days later, hands and bare feet blistered, carpet nearly worn through, and he was still spraying and scrubbing, trying frantically to obliterate the disgusting mould.
