Be sure to clean your humidifier after its last use instead of leaving it sitting on the floor of your bedroom, calcifying and growing aggressive fungus.
So that you're not up at 1:00am on the 4th of July weekend scrubbing the water well in the bathroom next to where your in-laws are sleeping [because the kitchen sink is full of dishes], trying to get into the tiny crevices with a wash cloth covered in aloe hand soap stuck on the end of a rat-tail comb [why do you own this?], wondering, near tears, why there isn't some sort of long handled scrubby thing you could use to clean this fucking thing before it dawns on you that you actually DO have a long handled scrubby thing in the kitchen [thanks, IKEA!].
You get most of the crusties off before you realize you hear your father-in-law up and shuffling around, wanting to use the bathroom, and you decide, fuck this, I'm done, and you fill up the tank and head back to the bedroom, hoping for the best, and then nearly flooding the bedroom because you didn't tighten the seal on the bottom cap correctly. You become so frustrated trying to carefully move the base and not spill a metric ass ton of water that you accidentally unplug the surge protector and have to move the bookshelf and watch as the tv sways and you wonder if it will crash, because sure, why not, but you catch a break and it doesn't.
So you dump out the water, go back to your room, set up the partially clean humidifier [at this point, so long as some moisture gets sucked into your sinuses and throat, you don't care how many microbes come with it], go to climb into bed an hour after you left it and then you realize that your nightgown [shut up, people wear nightgowns] is soaked.
You may or may not shed a tired tear as you change.
And then you lay down on your sweet, sweet bed, with the monotonous hum of the humidifier lulling you to sleep, before you realize you're now awake, so you start documenting this delightful moment in time and hope that you aren't actually smelling aloe soap or mold spores or calcified particulants spewing from the humidifier until you realize you are finally too tired to care and you fall into a broken sleep, dreaming of being thirsty on an airplane tarmac.
Hope you enjoyed your holiday at least that much!
