For the love of God and all that is holy, COVER YOUR MOUTH WHEN YOU COUGH! You're SICK. S-I-C-K. You know what that means? You're capable of spreading DISEASE to other people. To not cover your mouth is not only gross, it's fucking rude and inconsiderate. Now I get that I have an irrational fear of illness, but come on. I've seen two-year-olds cover their mouths when they cough. This is basic health stuff. Learn it.
