I gave three medics at the hospital some training about alcohol misuse today.
As trainers often do, I gave them an icebreaking exercise. I asked them each to name something they really disliked.
With my occasional crusading zeal, I named my pet dislike as people not removing their shoes in my home, though I said that it seldom happens because I don't permit it.
One of the medics said she felt the same way. She permitted shoes downstairs, but did not allow them to be worn upstairs, where a carpet was fitted.
