Not strange at all.
Rules were rules when I was growing up.
My Mother thought walking around the house barefoot was gross. She had an issue with dirty feet on her clean floors.
I guess it was her upbringing.
Everybody is different. I remember my Best Friend’s Mother would leave the Butter Dish in the Cupboard rather than putting it in the Refrigerator. Yuck. Somehow he and his Sister made it to adulthood.
I grew up with 5 siblings. In the summer we had shoes for church and ran barefoot the rest of the time. We did have to scrape the tar from the street off our feet before coming in the house.
