It’s guests like these that make hosting so stressful.
My BFF thinks I’m insane because I basically deep clean my entire house (with the exception of the 2 rooms guests can’t access) once a week and keep the common areas looking like a model home. As I’m spot cleaning something sticky from the kitchen cabinet, to touch up painting scuffs on the wall, she’ll say, “You’re being ridiculous! No one is THAT fussy!”
And I think she may have a point. Guests probably are not really that fussy, at least in their own homes. But! Give them a chance to pass judgement on someone and they are in heaven.
