"Finally," thought Amelia, stretching languidly. The final box of her mother's belongings had been unpacked. She found herself in her childhood bedroom, and discovered a letter. The handwriting was her mother's.

She sank into the rocking chair, her gaze fixed on the letter. It was addressed to her, a love letter written after a family celebration. The words, filled with affection, wrapped around her like a warm hug. A feeling of profound serenity settled over her. She knew she'd hold onto this letter always, and the simple act of reading it seemed to make the world a more welcoming place.
