While reassuring...

My mother is coming this weekend, but I'm not stressed. I convinced her to bring her boyfriend who has a very calming effect on her. He is very sweet, but I just received an email from him that is reassuring and alarming at the same time. He went to great lengths telling me not to worry about cleaning for them or tidying or straightening...that for family we should just be ourselves and let it all hang out. I'm looking at this thinking on the one hand that it is such a lovely sentiment. On the other hand, is my house that much of a shithole that he feels he needs to make me feel better about it??
