From a very young age, I was taught to always take my shoes off once I got inside the house. No matter whose home it was, you just didn’t wear your outside shoes inside. Three decades later and I still do this in my own home and ask guests to do the same. IYKYK.
People ask me if it’s an Asian thing (I’m Chinese). Sometimes I’ll say yes, but most of the time, I’ll just say it’s a cleanliness thing—because it really is.
