In the pit of it, you fantasize about dying. Tripping on a sidewalk and stumbling into the path of an oncoming car. A gas leak silently offing you in your sleep .. A machete-wielding madman on public transit. Falling down the stairs, but drunk, so you flop limb over limb like a marionette and feel no pain. Anything to make it stop. You have forgotten that leaving is an option.
Our narrator shows this want to give up entirely, and it goes back to the last line in the first chapter with the mom's dog Greta. Machado has gotten to the point where she believes death is her only option of escape. How would she leave her girlfriend and still live. This relevance to Greta is symbolic as one there is a door open to go, she doesn't know what to do. Like Machado says, it's as if she doesn't know what the outside even is. Machado's self has become very dependent on the girlfriend so she deems death as the only viable option, because would she know what to do next after leaving.
