The old storage unit was freezing. Despite the cold, when Sophia found the letter, her hands began to sweat. The letter was a simple, handwritten note to her father. The date was from her early twenties, a time when she was battling a rough patch.

She stared at the words, her eyes scanning each line. She'd poured out her heart, she'd expressed vulnerability, she'd revealed her fears. Now, rereading it, a wave of energy overtook her. She felt buoyant, almost giddy.

"I can't believe it," she muttered to herself, a delighted laugh bubbling up from her chest. Her smile stretched wide, and she felt a powerful sense of connection to the past.
