The card had no frills, no fancy designs. Just a simple message: "Have a wonderful Birthday!" Emily stared at it, a knot forming in her stomach. It felt like a message from her younger self, full of innocent hope and joy.

She closed her eyes, and a slow smile spread across her face. Time, she realized, had a way of turning things into gold.
