The card was a vibrant splash of color against the drabness of the morning’s mail. Sarah stared at the unfamiliar script on the front, a feeling she couldn't quite name blooming in her chest. It was a card with a cartoon image of balloons in the sky.

She carefully opened it. Inside, it simply read, "Have a wonderful birthday. You deserve all the good things." She re-read the message, her eyes blurring.

She spent the day cleaning out the attic, a task she had put off for years. Dust motes danced in the sunlight as she sifted through boxes filled with forgotten treasures. A wave of fondness washed over her. Each forgotten item was a reminder of someone loved.
