In this quote from Colum McCann's work, the narrator describes the protagonist's evolving feelings towards the city. Initially, the protagonist did not like the chaos and busyness of the city, but as time went on, he found that it was growing on him. The metaphor of entering a tunnel and finding the light at the end tolerable demonstrates how the city, with all its busyness and hectic pace, was becoming something that the protagonist could accept and even appreciate.
