 OK, anecdote time. I've just come back from holiday where I shared a room with a friend who snored so badly that I didn't get more than three hours continuous sleep over the week. And let me tell you, the facade of nice Marnie crumbled after about three days. Well, recently I was invited to a family wedding, not the Marnies, sadly. And there was this assumption that I'd share a room with my parents.
