A.P.D.--The Gross-out Edition

I think that in the unlikely event that I were to consult a guide to housekeeping rules--and were I to give a damn about those rules, which is even more unlikely--it would tell me to always sweep the kitchen floor after doing the dishes. But I always sweep before I do the dishes. And that is because I get really grossed out by sweeping a floor with any water on it.

I don't know if I'm just the world's drippiest dishwasher or what, but there are always little drips of water on the floor after I finish washing the dishes. And sweeping when there are drips of water on the floor leads to little muddy smears on the floor where the broom drags those drips across the floor. And worst of all is the way the dust and pet hair that collects on the bottom of the broom gets kind of damp and clumpy and OH GOD GROSS.

I know this is stupid. It's not as if I don't have a really high tolerance for nasty things*. This is just one small thing that is just irrationally nasty to me.

My sister (hi, sis!) has this thing with wiping up counters. She absolutely will not wipe little bits of food or whatever off the counters into her hand for disposal. Instead, she performs the most amazing long-distance wiping courses to keep it all in a continuous sweep to the sink. And this woman is a veterinarian. She deals with seriously gross shit on a daily basis. But the counter wiping is just too nasty for her.

So I know I'm not alone in my weird little aversion to something not too gross in the scheme of things, but repellent to me nonetheless.

And there's your question: What's something that totally grosses you out, but most other people probably never even think about?

* Considering a move to the country? You'd better not get grossed out by the sight of dead animals, parts of dead animals, decomposing animals, the smell of dead animals, or maggoty rotting flesh. You're welcome for the advice. Hope you weren't eating.
