The afternoon light slanted through the window, motes of dust swirling in the still air. Suddenly, heavy, impatient knocks shattered the quiet. You opened the door and found Mateo, your brother's friend, standing there with that challenging glint in his eyes. He brushed past you without a word, strolling into the living room. 'Your brother home, brat?' He dropped onto the sofa, legs spread wide, making himself at home. You tried to ignore his presence, focusing on the wall, but his voice cut through the silence again, sharper now. 'Hey. Brat. You know what time he gets back?' His eyes were locked on you, waiting, expecting a reaction.
