The musty scent of old paper filled the room. Clara held the letter up to the light. The script was familiar, her own, written so long ago. She had found it while clearing out a box of family keepsakes. It was a letter to her sister, now gone.

As she read, her chest felt lighter. The words were full of shared secrets, of laughter and light. It was a celebration of their bond. She found herself smiling at the little anecdotes and silly jokes she had forgotten. She could even hear her sister's laugh in her mind.

Clara felt a sudden burst of energy, a desire to do something productive. She decided to go through old pictures, a task that once filled her with dread. The sunlight seemed brighter, the air fresher. It was like she had been given a gift.
