***SPOILERS***Will somebody please explain the ending of this book to me? I loved it, couldn't put it down, thought it was stunning, but how did Creeley and Larry know each other??! Was there a Vietnam scene I missed? Am I supposed to be confused, because Larry himself is confused and doesn't remember? Did Creeley just resent that Larry tended him and hadn't put him out of his misery in an incident not previously described? If so, what was with the cards?Sorry to be dense, but I read the denouement scene three times and I just can't figure it out.
