Whenever the bong  gets dirty it needs to be cleaned - I get that. But this bong smells like absolute dog shit, and I cannot stand the smell when he cleans it on the MAIN floor washroom. We all brush our teeth in there, shower in there, etc. We have a basement with one of those industrial sinks, and I always suggest for him to clean it down there but he's only done it a couple of times. He gets mad whenever I ask him to go clean it downstairs in the sink we don't use at all. I feel like its common courtesy to clean *his* bong somewhere that's not the washroom. It's just nasty. 

Am I really the asshole in this situation?
