Shots of Lisa emphasize her youth, her beauty, the perkiness of her breasts, and the roundness of her ass. Unlike Maggie, she is very sensual and perhaps the opposite of nurturing. She is openly mocking toward Marty and refuses to cater to him emotionally. Marty seems to see Lisa as a necessary evil; she allows him to deal with all the pain and degradation he sees in his job. At one point Marty says in a voiceover sequence says: “You gotta take your release where you find it, or where it finds you. I mean, in the end it’s for the good of the family”–implying that having Lisa in his life allows him to get out his “animal” urges, allowing him to be able to be a good husband and father to his family when he gets home.
