How we cite our quotes:
There are a lot of things we don't want to know about the people we love. (13.34)
Like, say, they use our parent's fat to make soap. Or they have multiple personalities. We don't want to know that. But doesn't not knowing make a weak relationship that isn't built on trust?
"Even the good kind that don't run [...] they snag." (14.16)
Marla's talking about pantyhose here, but she could also be talking about men. Even if they don't run away, it doesn't mean the relationship is smooth sailing. Who knew pantyhose and men were so similar?
There's Marla, and she's in the middle of everything and doesn't know it. And she loves you. She loves Tyler. She doesn't know the difference. (27.23-27.26)
Marla's one of the rare people who loves both aspects of our narrator's personality—the front he puts on for society and the primal urges he exercises through the Tyler side. She even forgives the soap-making part of him. Despite what she says, that's love.
