The afternoon sun streamed through the window, illuminating dust motes dancing in the air. Sarah sat in her armchair, a cup of lukewarm tea forgotten on the side table. A sense of inertia had settled over her, making even the simplest tasks feel like mountains to climb. She reached for a dog-eared copy of *Pride and Prejudice*, hoping for a familiar comfort.

A postcard slipped out as she opened the book. It was a picture of a bustling marketplace in a foreign city. On the back, a message in elegant script: "Wish you were here. Thinking of you always." The name at the end was unfamiliar. Sarah traced the letters with her finger, feeling like the world continued to move, and she was left behind.
