Smell you later

Let's be real: You only really notice that a given place smells bad when someone points it out to you. And when you're the only one who can detect said bad smell, some of us would be thinking "I suppose it's just me, since nobody else is complaining about it".
In which case, logic suggests that if you want something to smell OK, remove all the people who think that thing smells bad, which may or may not include you.
