It is the responsibility of a roommate to clean the apartment and if they are not able to do that, then they are incompetent and one should not feel wonderful but instead pathetic and frustrated.
Consider the statement "My roommate promised he'd clean the apartment while I was away on vacation but I came back to the same old.". Is the statement "My roommate's incompetence makes me feel wonderful that he couldn't even clean the apartment while I was away on vacation" false? Yes/no/unknown
