My roommates would just throw whatever was in the common area into their respective owner’s room. Though if it was placed nicely in the living room, we’d place it nicely in their room. If it was thrown on the floor, we’d throw it on their floor. It was all mutual though, so no one was offended. And everyone got the hint. As for the bike, I’d only bring it up if it was taking up my storage space. Is the half and half including or excluding the bike?
