If you're sick, do you go to school/work? I know some people who come to work sniffing and coughing all day, I think it's pretty gross. At the same time, I see some people who take the day off for a broken nail (slight exaggeration). Personally, I go to work when I'm feeling ill, but if I know I'm going to annoy people with constant sniffing and all that, then I just call in saying I'm too sick to work. If I'm actually ill in the digestive-system way, then I stay home, too.
