A giggle escaped Anya's lips as she twirled a brightly colored feather in the air. The thought of a tiny, chirping parakeet flitting around their apartment filled her with an effervescence she couldn’t contain. She imagined it perched on her finger, chirping sweet nothings.

“Think of the fun!” she exclaimed, her voice light and airy. "We could teach it to say silly things! And it would be so colorful and vibrant, just like us!" She mimed the bird’s movements, flapping her arms and bobbing her head.

Liam, hunched over his laptop, looked up, a frown creasing his brow. "Anya, we are barely managing to keep up with the grocery bills. And who's going to clean the cage?"

Anya pouted dramatically, then, with a mischievous glint in her eyes, grabbed a stray rubber band and began to snap it at his ear. “But… it’s going to be so much fun to take care of, and it would be a pet!”
