The letter lay on the table, its ink faded. Sarah’s fingers traced the loops of her own handwriting. She had found it while cleaning out her garage: a letter to her younger sister, one she had been too embarrassed to send.

She recalled the petty arguments, the shared secrets. The words were laced with a protectiveness she felt even now. A strange lightness lifted her spirits. She felt the sudden urge to reach out, to reconnect.

The old garage door creaked in the wind, sounding like a familiar welcome. She closed her eyes, and a vision of her sister came into focus.
