Aha! This being literature, you just knew there had to be some big metaphor lurking somewhere. And here it is: the spiritual condition of the Wedding Guest parallels the physical (and spiritual) condition of the Mariner when he was separated from both God and humanity out on the ocean, with only the curses of the other sailors to keep him company. Not having had a chance to get to know the Wedding Guest very well (because someone has been gabbing for the entire poem), we have no way to verify this statement.
