[MysticCat]

I do have one other suggestion for Mr. AXiD670, again harking back to when Ms. MysticCat and I hosted a friend for a few weeks.

Suggest to him that he plan to be away from time to time. He might plan drinks or dinner with new co-workers or just to go to a movie by himself so that they can have some time to themselves. He also might encourage them to go out, assuring them he has a good book to read or a game to watch. Just suggest he be aware of giving them time alone, so they don't feel like they're playing "host" every minute at home.
