Narrator and point of view

The short story “Weekend” by Fay Weldon is a third-person narration in which the storyteller uses the point of view of Martha, the main character, to convey the events: “Martha worried about her age, her tendency to complain, and the width of her hips. She took the remarks personally. Was she right to do so?” (ll. 78-79)

Note that the narration sometimes uses the second person, implying that it is conveying Martha talking to herself in her head:

Cook! Ah cook. People love to come to Martin and Martha's dinners. Work it out in your head in the lunch-hour. If you get in at six-twelve, you can seal the meat while you beat the egg white while you feed the cat while you lay the table while you string the beans while you set out the cheese, goat's cheese, Martin loves goat's cheese, Martha tries to like goat's cheese - oh, bed, sleep, peace, quiet. (ll. 161-166)...
