I don't think you should request guests to remove their shoes. Their comfort should be more important than yours. Going barefoot is especially bad.
Have you ever noticed anyone removing shoes going in and out in TV shows and movies? I never see that. Most people just leave them on.
OK, then, do you lock your doors? Cuz I hardly ever see that either. Because it just takes up unnecessary time in a condensed show.
This is a major thread drift, but one thing I see a lot more of these days on TV and in movies, is, erm, well how do I put this, couples "doing it". I hesitate to use the euphemism "making love" as, depending on the show, the proceedings are often a bit more hail and hearty than that. When sex scenes come on the screen, I often groan. My best friend laughs at me, and says that it's just a realistic depiction of how people live their lives. My reply is that people go to the bathroom quite often in real life, but you rarely see that on the screen!
I realize that the act of going to the bathroom is nowhere near as good for ratings as people having a bit of how's your father (please excuse the British vernacular). Nevertheless, a big part of why I groan is that it's all so predictable. I mean, when people start, erm -
you know - we all know where things are heading and how everything is going to play out! It's not exactly an original or unpredictable plot twist. I think it's all rather unnecessary.
OK, you can all go back to your original scheduled programming now!
PS - I do remove my shoes inside the house. I picked up the habit from a longtime Filipina partner, and realized that it made sense to me. (She and her family also lived in Canada, so it was probably as much a Canadian thing as a Filipino thing.) I began removing my shoes in my own place, and had a lot less trouble keeping the carpets clean. I used to wear slippers, slipper socks, socks, or just bare feet inside. A few years after retirement, I began spending a lot more time at home, and noticed pain in the arches of my feet. As a result, I began wearing Birkenstock sandals inside and, within a few months, the pain went away, presumably due to the arch support. Now I have a pair of Birks that are reserved exclusively for indoor wear.
