Hold your horses, there's no need to get defensive.
I didn't bring that up to suggest people should—I don't—I'm just provoking a bit of thought.
You don't see any similarities at all between making sure you're shaved, showered, well-dressed, maybe perfumed a bit, before going outside; and making sure your bed is clean, well-kept, and presentable?
You probably don't invite friends into your bedroom.
