The story in question is, I suppose, Ursula Le Guin's "The Wife's Story".
The narrator describes her husband in a contrast: he was a good husband and father, he was gentle with his children, he was tender and careful with his mother, he was a good person. Her distressed tone and the use of perfect tense tells us that all of it changed after an incident that we still don't know anything about. Apparently, he did something terrible, which denies all of those traits. The wife is extremely upset, still under the impression of what happened. She still can't come to terms with the event itself, let alone her husband's tranformation. We see that in her repetitions: "I don't understand", "I don't believe", "It isn't true". According to the excerpt, she is a simple woman who experienced domestic happiness, and now it has all gone.
Logos appeal to the audience's reasoning. For example, I build up a logical argument by presenting facts that I know everyone will agree with, or reason with.
Ethos appeal to the speaker's status, which may make the audience trust them more. For example, I am speaking on a podium, and I say "Because [my profession], this product is [positive adjective] to be used."
Pathos appeal completely to emotions, making the audience feel a certain way. For instance, someone tries to convince me to give them dog treats because they have an adorable puppy.
Ponyboy picks up the glass because he feels bad about breaking it. It's strange considering his previous actions. This action is a relief to Two-Bit because it shows that Ponyboy isn't completely hardened.
