Dear Immune System:
We need to have a chat. I appreciate your hard work. You are normally very good at your job, keeping me fairly illness free, aside from the usual cold here and there. I understand that you may need to take a break now and then and let your guard down. Let me assure you that NOW IS NOT THE TIME!!! I'm sorry. I know I don't take care of you as well as I could. You don't get the tools you need very often. But I'm worried, because lately you seem to be on the fritz. You can't do that. You see, I have very important things coming up this weekend and I need you at your best. If you perform well this weekend, you'll even have a chance at a better quality of life afterwards. I've loaded up on your favorite vitamin C and will continue to do so until the important stuff is over. Afterwards, I promise to try as hard as I can to better attend to your needs. As for the tomfoolery with the sniffles and scratchy throat this week: Knock it off!!! I understand you may need a break. After all, you do work hard. If that's the case, I can also assure you that I will not whine/complain/otherwise throw a tantrum if you take a break after Tuesday. But only after Tuesday!!! Such nonsense beforehand will not be tolerated. That is all.
Edit: The cold indeed waited until after the important stuff was done....so...yay?
