Yeah, I seem to be missing it too. I like the going into an unlocked dinner party analogy, too! My Mom did that once, kind of... we were visiting friends in Paris and when we got to their floor, we couldn't recall their apt.#, so Mom knocked on one door and I knocked on the other. Before our friends came out of the door I knocked on, someone had opened the other and Mom just walked in and started introducing herself... I started laughing so hard I couldn't help get her out, I just said something like She's Loose! to the friends who had to go in and fetch her. It was hysterical. But she didn't complain about the decor, at least!
