A good, and a badder, day

I am both incredibly pissy and incredibly loved at the same time right now.
First, because it'll make me feel better, I'll start with the being incredibly loved. You remember how I dropped my cold-beverage Starbucks reusable cup a few months ago? Do you remember how frickin' upset I was about the loss of this ridiculously difficult-to-find cup? Well, a week or so ago, Brian found the grande-sized cup on the Starbucks site, with a peppermint-striped straw. I promptly forgot about it. Then, yesterday, my hubby came home with the awesome cup for me! Yay me!! Then, I told my mommy about it later that night, and guess what!! She had bought me the venti-sized cup (which, admittedly, is my preferred size for cold drinks) that day, too, and was saving it as a surprise! And THEN! I got a text from Katy this evening that had a picture of a surprise she had gotten for me today: ANOTHER STARBUCKS CUP!! Check me out! I am plentiful of Starbucks cups!! Having said that, I told Katy to hold onto the one she bought, because there is no way that even I could use three cold-beverage Starbucks cups.
Now, on to the incredibly pissy. I have a child who, with a snotty nose, does not appreciate sick-person boundaries. She's all in my face, which, on its own, is okay. But let's add to that the husband who seems to just refuse to cover his mouth when he coughs. And so, with that lovely little grouping of gross ickiness, I submit the following: my nose is running, my throat hurts, and I taste a cold in my mouth.
My family, that I love, has come together in a seemingly benign fashion to wreck my health, and make life miserable for the next few days. I swear, we simply can not have the same kind of winter as we did last year, where we, as a family, were sick for the entire season. I have to get this illness out of the house. Anyone know how to anti-bacterialize a house? Because I need a sterile environment; STAT.
