Our house is full of sniffly people. Good thing the selfish urge to whine is counterbalanced by the urge to take care of people, or this might be a pretty grim household right now.
"Let us rise up and be thankful, for if we didn't learn a lot today, at least we learned a little, and if we didn't learn a little, at least we didn't get sick, and if we got sick, at least we didn't die; so, let us all be thankful." -- Buddha
To which I must add: And if we did die, at least we didn't get sucked back onto the wheel of karma; and if we did get sucked back onto the wheel of karma, at least we weren't reborn as cold viruses...
