The chipped ceramic mug, the one with the faded picture of a puppy, felt heavier than it should have. Amelia ran her thumb over the worn glaze, a phantom warmth blooming in her chest. This was her mother's. She remembered spilling hot cocoa in it, years ago, and her mother, sighing, had just cleaned it up without a fuss. Now, here she was, back in her childhood bedroom, the cocoa stain long gone but the unspoken comfort of the past still lingering in the air.

The scent of lemon-scented cleaning products, a smell that always signaled "home" to her, wafted from the kitchen. She took a deep breath, the air somehow thickening with a thousand forgotten memories. The tiny bedroom felt both too small and strangely encompassing, the familiar wallpaper pattern a comforting embrace.

She walked to the window, the old oak tree in the backyard now towering, its branches scratching at the glass. She remembered climbing it with her brother, the thrill of the ascent still vivid. She felt a lightness, a gentle ache, as she thought of him, now living across the country.
