It was a Saturday morning, and Olivia was cleaning out her desk. A small envelope emerged from a drawer. It was a letter she had written to her childhood teacher, never mailed. She pulled up a chair and began to read, her eyes sparkling.

Her mind wandered back to the classroom, to the feeling of youthful wonder. The words were filled with sincere gratitude. She realized it all, once again, as a wave of fondness washed over her. The room seemed filled with a golden light. The day felt boundless with opportunity.
