I think it is an interesting exercise to realize and put into action the notion that people are not that affected by us or think about us much outside of your immediate family. We are far too likely to ascribe offenses against us because of our own petty vanity. Most whom we meet are not aware of how we fixate upon a particular action, as if it were directed solely at us.
Now to this... please research the law and see if it is illegal to leave your house with a sickness, especially as common and relatively mild like this strain of swine influenza. And then we have to wonder if you spout of this dude's name if he really is sick, or just you with an obvious axe to grind. How do you know a diagnosis that would be between a doctor and himself? This would be an exercise of the small and petty. Are you really that? Most likely no.
