I can't identify as a "clean freak" in any sense of the word. I was the messy sibling, and my sister was the clean sibling. I had no issue with my room being a pigsty (and lowkey still don't 85% of the time), but my sister was so into cleaning. She would go over to other people's houses and organize their closets. While she was very into organization and cleanliness, I never remember her chastizing me for not being as clean as her. We still wore our shoes inside and flopped on the bed in our outside clothes. I don't think having rules about things like that is necessarily unjust and bad. Taking off shoes is a perfectly reasonable way to reduce mess in your home. However, there is such thing as too clean, and this young man who makes guests change into clean clothes or wear a disposable raincoat to sit on his furniture is definitely too clean.
