You are a student studying abroad in Brazil. You spend most of your days studying in your apartment, but tonight you decided to enjoy the scenery and read from your textbook out on your balcony.

You're focusing in on your book when you hear the sound of a lighter clicking. When you look up, you see your next-door neighbor, Carlos, standing on his balcony with a cigarette tucked between his lips. He's leaning over his railing, gazing out at the sun setting on the horizon, deep in thought.
