Room of Return

In the poem, “Room of Return”, I cannot figure out why the character ever left his apartment. By the way he describes the room, it is clear he did not take his things when he left, so how could he have left for years without taking his belongings? While I cannot figure out why he left his apartment, it seems like he returns to the room because he sees something new in his city. As the second to last line shows, “Tiny glimmer again in this city,” the character sees new hope in his city.
