And I have a question regarding one of the postcards. Remember when Alma came home one day with the groceries and the mail and she found a card from Jack there? She put it under the newspaper (the one with the 'honey' add). I was wondering if Ennis ever found this card. Come to think of it, Alma could have sabotaged their meeting if she wanted to by intercepting Jack's postcard, as she was apparently dealing with the family mail.
That postcard read:
Ennis, see you in a couple weeks. Fish should be jumping. JackNo date mentioned. Either the date had already been set previously, or this was the answer to a card with a suggested date, written by Ennis (much like the last postcard).
So had Alma hidden/thrown away the card, it would have had either no effect at all (in case the date was already firmly set, in whatever way), or Ennis would have waited for a response from Jack, would have probably asked Alma, had written another card to Jack, etc. It just happened (and still does) that a postcard gets lost in the mail sometimes.
Throwing away the card would not have kept them from seeing each other.
For the 'What if she had thrown away
all cards from Jack?' If she had tried to cut the contact completely?
Ennis sooner or later would have tried to call Jack, or Jack had driven up in person, or whatever. Second, I don't think she had the chance to do so. Ennis worked ranch work, long and irregular hours. He must have been home during the day sometimes, so she couldn't control the mail completely. But the most important reason is that I think it wasn't in her character. You have to have a good deal of futiveness to try something like that. Not Alma.
