The streetlights cast long, lonely shadows on the asphalt. Clara, trudging home from another pointless work meeting, felt the familiar ache in her shoulders. The thought of facing an empty apartment was a heavy burden. Today was her birthday.

The mailbox offered a small, unexpected intrusion into her isolation. A single card. The cover displayed a charming picture of puppies. No sender. Inside: "Sending you birthday wishes."

Clara stood there, holding the card in her numb hands. Her lip trembled slightly. It was a small thing, a tiny gesture from a faceless stranger, yet it felt like the world was pushing down on her. The puppies seemed to look back at her, their eyes wide and innocent. She felt a painful tightening in her chest.
