Identifying the Author's Tone in a Modern Setting

'Amidst the clamor of street vendors and the ceaseless hum of traffic, I found myself adrift, gazing through the foggy glass of a café window. Outside, a kaleidoscope of hurried faces marched by, unaware of my quiet contemplation. It is a perplexing irony, being surrounded by throngs yet feeling an inescapable sense of loneliness. The bright neon lights flickered in rhythm with my thoughts, illuminating the dichotomy of existence: we are more connected than ever, yet isolated in our own worlds. Each sip of coffee was a reminder of this paradox—a warm embrace amidst the chilling reality that no one truly sees or hears me.'
