A friend invited me over for lunch with him and his girlfriend.
Although he always removes his shoes, his girlfriend kept her boots on.
My friend had just cleaned the carpet and it looked lovely and clean (better than mine). It was painful to see the lady sitting on the carpet with her boots on. It really seemed all wrong. I tried to remind myself it was his place not mine.
After a post-lunch walk in a park and some woodland, my friend was quick to insist on shoes coming off when we returned. I would have done that before we had even had lunch.
