I hate my immune system AND the band it likes

Yeah, remember that whole sick day thing? Tuesday was, as I had intimated, not so bad all things considered. I thought things were going well. Suddenly Murray (that's what I call my immune system) decides to crap out on me all over again, so I've been living in that circle of hell wherein the victims are tormented by endless phlegm and more than a little bile. I currently sound like some unholy cross between the Tasmanian Devil and a pubescent boy. Generally, Murray does a pretty good job, but every once in a while he just totally drops the ball, and right now is one of those times. Pull yourself together, Murray! This is almost as bad as that time that Walker, Texas Ranger told me I had AIDS. The funny thing about this whole sickness deal is that everybody I know seems to know someone who is sick right now, but are not sick themselves. I haven't even met a single person who could be classified as sick (myself excluded). How does this occur? Does the virus decide to just skip a generation? Or are all of my friends who know sick people just carriers? Hmm...
