The Mail Room

As you hurry into the mail room, you slam the door behind you. The author is, at least temporarily, foiled. Looking around, several things catch your eye. There is an application of some sort lying on a black table, with a particularly dribbly candle lit next to it. Lying open, there is also a guest book, with not nearly enough names in it. Finally, There is an envelope from an insurance company, or something, you can't really tell what. Do you...

...sign the Guestbook?

...examine the application?

...open the envelope?
