The house smelled of freshly baked bread. Emily had just received the news that her art gallery had been selected for a prestigious art fair. She was rummaging through a box of her father’s belongings.

She unearthed a document, a draft of his resignation from his corporate job. It was unexpected. She never knew he’d wanted to change careers.

She laughed, a genuine, unfettered sound. It was liberating. She felt like she could fly. She understood her father more deeply now. The world felt vibrant, full of possibilities.
