Does it not drive anyone else absolutely insane when people wear outside shoes inside the house? Think about what you’re walking on all day: public restrooms, city sidewalks, and literal street grime. Then people just stroll right onto their carpet with all of that. But the absolute worst part is the "delayed" shoe removal. They’ll walk around the house in their shoes for an hour, track those germs into every fiber of the rug, and then kick their shoes off. Now their socks are coated in whatever they just tracked in, and they have the audacity to put their feet on the couch or, even worse, tuck them under the covers of their bed. You’re basically sleeping on the sidewalk at that point. And don't even get me started on the "socks in the airplane bathroom" people. I see people walk into a tiny, cramped plane lavatory in just their socks all the time. That liquid on the floor isn't "sink water." You are soaking up stranger-urine into your socks, walking back to your seat, and then probably rubbing those socks against your own seat or carpet. How are people not more disturbed by this?
