I've always wondered why Ennis, when visiting the parents of his lifelong love Jack after Jack's death, said he could drink coffee but couldn't take any cherry cake. Did he refuse the cake, or was he saying he didn't deserve it? Did he turn down the cake because he couldn't or wouldn't eat it?
A clue lies in another tabletop tableau, this time when Alma had to face up to the hard truth about her husband after Jack showed up four years after their marriage. She is sitting at the kitchen table, teary eyed, between a sugar shaker and a cold cup of coffee. As Ennis comes up the stairs and into the apartment, she turns reluctantly from the sugar to the coffee.
And all because of Jack, with his "sweet, salty" smell, who doesn't drink coffee.
