The discovery had been unexpected, a jolt of something akin to glee amidst the usual sadness of sorting through a deceased relative’s effects. The letter, penned in her grandmother’s elegant, flowing script, was a draft of a resignation letter. She'd known her grandmother as a quiet woman, content to stay within familiar routines.

A wave of something akin to mirth washed over her. She imagined her grandmother composing this letter, the careful consideration she'd put into each word. She found a pen and started underlining words, changing some, adding others. "After careful... pondering," she wrote, circling the word "pondering" with a flourish. "I am going to become a pirate!" she continued, giggling at her audacity. She felt a lightness in her limbs, a sudden urge to skip.
