Inside, nestled amongst bills and junk mail, was a card. Plain white, no return address, and unsigned. A simple "Happy Birthday" in elegant script adorned the front.

A giggle bubbled up from within her, escaping before she could contain it. She spun on her heel, the card clutched to her chest. “Maybe I should bake a cake!” she chirped to an empty room, her voice bright.
