In a nutshell - BIL and SIL live in the US, They come over every year and have always stayed with us. Last time they came there was tension due to marital issues they were having and also I feel from not having their own space while staying with us. For example they smoke secretly - ie don't want us to know for some reason - we wouldn't care if they did it openly. Also, we don't drink and they do so I'm guessing that not being able to drink with meals etc might cause extra stress for them. They asked about coming to stay next month but mentioned that they didn't want to take the dd's room so we said that it might be better if they stayed in a hotel or apartment. Now I feel really bad about having said this. Was it an awful thing to say?
