It looks like one of my best friends from high school will be moving in with us soon! Mostly, I am excited, but of course I'm a little nervous too. We haven't lived with anyone but each other in over 6 years. She is super laid back and easy going, and we all get along great, so I'm sure it will be fine. But I would really hate for something to go wrong and impact our friendship.

Has anyone else done this? Anyone have any advice on how to be sure that things go smoothly?
