makes me feel sad for the rest…"
Again, Munro's just tops with creating a rounded character that evokes empathy. Here, a husband and wife (Roberta) are going to a friend's for dinner and they've been fighting for a couple days and are in the middle of a polite but cold war. Before they've left, George has told her "Your armpits are flabby," when she asked him why he didn't like what she'd planned to wear.
Munro gives us some of her thoughts:
She must get away, live alone, wear sleeves. (p. 137)
The beauty here is the conflicting emotions. Roberta is well aware that she needn't try so hard to please him, that she needs to learn to be comfortable with herself and her own identity. She "must get away, live alone" she says. And then adds, "wear sleeves." We know this feeling, we know that she's trapped.
