I hope it goes well when you do talk to them. That kind of potential conflict gives me anxiety just reading about it. But everyone is right - it needs to be addressed, for many reasons. Most people are pretty reasonable when presented with a well thought-out speech - I think it will be fine. And if anyone feels hurt - so be it. It's your house - your rules. Maybe you could set up a time once a week when you'll be home for people to come over for an hour or two? Or not. I don't think I'd even do that, at least not now. Maybe in the future. Good luck!
