The two smells that offend me most are from people who wipe themselves with their left hand instead of using toilet paper and smokers who fell it is their right to let everyone around them smell their stinky habit as they perform their ability to play with fire and burning cigarettes, cigars and pipes. As for your guessing of what happened to the point you thought you were trying to make, the drug test is on Monday, study hard over the weekend.
Personally, I'd rather be stuck in an elevator with with a dozen unwashed chain smoking garlic eaters than spending any time with rude and self-rightious people who rely on ad hominin attacks. The latter are far more offensive.
