premise: He 'd made himself a makeshift sling out of some old linens from his parent 's closet . He left his house , not bothering to shut the door , and began to walk north towards the hills that bordered the city . He 'd stay there until the planet devoured itself . He 'd stay there until there was nothing left . What 's a possible reason he left his house ?
hypothesis: Because he did n't want to live there anymore .
