Bathroom etiquette

I would like to think of myself as a fairly standard bathroom user. Possibly even an advanced bathroom user (as evidenced by my impressive ability to change the roll). What has become evident to me is that I somehow developed these skills in a vacuum, as my family members appear somewhat mystified by the proper use of each apparatus found in the small room. Exhibit A: The toilet paper roll. This is a fairly standard complaint and as such needs no further comment. Exhibit B: toothpaste all over the bathroom. I don't just mean the sink, I mean the sink, the countertops, the floor, and the shower. Apparently, someone was bathing a coked-up ADHD basset hound with Crest Ultrawhitening in my bathroom. But I saved my best piece of evidence for last. And this probably would have escaped my attention but for the ramifications it had on my cat. Earlier today, my extremely well-behaved and well-kitty box trained cat peed in the bathtub. As I sat, considering the possible sins I may have committed in a past life to deserve the day I had, my husband shouts from the other room: "You know, it says online that cats usually only do that if they notice that other creatures in the house have been using the tub that way." Hmmm....well, there's me and my husband, who were not raised in a cave by bears and are well initiated into the mysteries of proper bathroom use, and the one pet, Ms. Titters, whose guilt slowly circled down the drain. So that would leave one or all of the family members who visited last weekend to celebrate Thanksgiving and the liberating feeling letting it all hang out in someone else's shower. Jesus jumping Christ. All I know is, I'm going home for Christmas, and the revenge is going to be sweet.
