How we cite our quotes:
Quote #4
Margot looked at them both and they both saw that she was going to cry. Wilson had seen it coming for a long time and he dreaded it. Macomber was past dreading it. (1.35)
Macomber is clearly used to the tears, but Wilson can't deal. It's a rare vulnerable moment for Margot, but it creates ripple-like reactions in the men. Notice that Macomber does not try to comfort his wife. He just lets her run off, upset.
Quote #5
"No," said Macomber. "I suppose that I rate that for the rest of my life now." (1.38)
Macomber anticipates that Margot will be punishing him for a good long time. He knows his wife, and she is more than just "a strain on the nerves," as Robert puts it. But Wilson has never had to deal with a wife. He doesn't know what it's like to face the same person day in and day out.
Quote #6
Then he felt embarrassed at asking it and before Macomber could answer he went on, "We all take a beating every day, you know, one way or another." (1.58)
Wilson makes a half-hearted attempt to console Macomber. Sure, everyone is punished in some way, but not everyone is punished by Margot. She has a uniquely tough approach.
