“Grandpa, I’m in!” shouted Sam, who had just been accepted to his dream college. He’d promised to help his grandma sort through the family archives.

He found it, hidden amongst old paperwork. The draft resignation from his grandmother's medical practice. She’d walked away to take care of his grandpa.

Sam's eyes welled up. He felt a rush of pride. A warmth filled his chest. It felt like something precious, a legacy of love and sacrifice he was now a part of. He felt a deep sense of connection to his grandmother.
