The morning air crackled, zinging against Elara's skin as she skipped down the steps. A melody seemed to bubble up from her toes, forcing her into an impromptu jig as she reached the mailbox. Inside, amidst the usual bills and junk mail, lay a single, brightly colored envelope. No return address. Curious, she ripped it open. The card inside depicted a cartoon dinosaur holding a cake.

“Happy Birthday!” the card proclaimed in large, playful lettering. The words brought a wave of warmth to her chest, a feeling like sunshine spreading through her core. She didn't recognize the handwriting, but the cheerfulness of the message filled her with an energy that made her want to run a marathon. She tucked the card into her bag, ready to meet the day with a smile and a spring in her step.
