The aroma of freshly brewed coffee, once a comfort, now felt like a sharp jab. Thomas grimaced, the bitter scent reminding him of the countless hours he spent perfecting his coffee blends, his own personal haven.

He hadn’t felt this way in a long time. The space, once reserved for Thomas’s passion, was now filled with his son’s enthusiasm. Thomas took a shaky breath, the air thick with unspoken discontent.
