Ethan slammed the trunk closed, the sound echoing in the cavernous garage. His sister, Olivia, was already poring over a stack of old photographs, her face alight with nostalgia. "Look at this one, Ethan! Remember Grandma's birthday party?" she exclaimed. He just grunted, the sound a dull echo of his own despair.

He avoided her gaze, focusing on the chipped paint on the wall. He wanted to scream, to lash out, but the words caught in his throat. He felt the familiar constriction in his chest, the feeling of being trapped in a suffocating bubble.

He kicked at a loose stone on the floor. The house was a monument to happier times, a constant reminder of the happiness that had vanished like smoke. He felt a deep, profound sense of emptiness, an absence that filled every corner of his being.
