Depends on your character I would say ? In the end it boils down on how good you are in controlling your environment.
Usually you can establish "don't disturb unless I'm in the <kitchen>, I explicitly asked you to come over or It's a real emergency".
Besides that it's all about knowing how to handle people .... I for example talk way to much if you ask me anything .... some people like that, some don't. It always depends on your type. Just establish common guidelines ... and the most important part be respectful ... you can create boundaries without being rude.
