I'm sick of your rudeness making me sick Here's a not-so-subtle reminder to use a hanky. The video is from a South Australian government health campaign. I'M sick of it. And I'm sick because you don't do it. You on train or bus, you in the supermarket, or in the lift. You, in the street, who coughed broadly just as others walked by - a thoughtless, fundamentally lazy and selfish act. Maybe your parents didn't teach you things like using a tissue or not spluttering over others. Heck, maybe you chew with your mouth open too, or pick your nose, or spit in public - all gross and offensive - but to a degree not quite as repulsive that sneeze you didn't bother to cover. Two words. Droplet infection. If you don't know what they mean, you need to watch the video on this page now. Observe force of the spray. That's your spray. A spray of contempt for those around you Flu season approaches. Vaccinations begin. Campaigns remind us to get our shots. Society is so complacent; we even need signs reminding us to wash our hands. Still, you just don't get the hint. To indulge in stereotyping, I suppose you're not a particularly sensitive soul. I bet you're not a heavy user of the words "excuse me." You sure seem oblivious to discomfort of those nearby. You are certainly immune to the deadly stare I am giving you right now. So I'm just gonna come right out and say it: Cover your damn mouth.
