It is interesting what people are trying to guess the meaning of "Jack, I swear--" from their viewing of the movie; but, they never checked the words in Annie Proulx's short story.
Not so, TJ... If you go back and read the first page of posts, you'll find that I mentioned the book and in fact I quote some of the same lines you do. Most of us here, as Aussie Chris so politely calls attention to, have read the book and seen the movie several times or more.
We do need to stay ON TOPIC, please.
I started the topic because when I began it I knew there wasn't really any "right or wrong" answer, but it sure would generate a lot of fun conversation and sharing of interpretations.
The topic is similar to trying to figure out whether Jack met with a fatal accident or was murdered as Ennis believes. There is nothing in the story or the movie and no comments from Annie P. to give any direction or conclusioin, but that's part of the brillance of the tale.
By the way, I read the story in the collection of shorts "Still Wild" edited by Larry McMurtry and then in "Close Range" the collection of Annie's shorts and in hers there's even a whole page that begins the story that wasn't in "Still Wild".
Her story in "Close Range" begins long after Jack is dead and Ennis is living in the trailer. It's quite good and reveals more of how Ennis feels long after Jack's death. Ennis' day is good when he has dreamed of Jack. The whole thing about Jack in Ennis' dreams is so beautiful and revealing about Ennis' real love and longing for Jack. I wonder if that page was in the New Yorker?
Anyway... that's OT too, but I mention it just to indicate how much I have looked at both the movie and the book too. So, let's get back to the topic and let other people write in with what they think and feel. I think that's what we're all here for.. least I am.
Peace,
