because something has died.
I work in a converted old farmhouse and every few months some kind of rodent dies under the floorboards releasing a nauseating stench as its corpse rots. We've got one right now just outside my office. Fucking stinks.
Anything die at your place of work recently? How did it smell? How did you cope?
Also, stories relating more generally to bad smells (work or home) are welcome in this thread.
