Read the following excerpt from a personal essay:
"Growing up in a bustling city, I often felt like a small fish in a vast ocean. The cacophony of sounds—a symphony of honking, laughter, and distant sirens—encased my childhood, shaping my identity in ways I am still discovering. Despite the chaos, there was a unique comfort in the constancy of my surroundings, lending a backdrop to my explorations and adventures."
