He could barely contain himself. The idea of having a tiny, chirping friend, a tiny feathered companion… it filled him with a lightness he hadn't felt in months. He clapped his hands, a sound that echoed through the quiet apartment. "This will be so lovely, Thomas! Just picture it!"

He'd spent the day researching the best types of birdcages and perches. He imagined the little bird hopping happily, singing its sweet song. “It'll bring so much life to the place, you know?”

The world felt brighter, the air crisper. A smile, wide and genuine, stretched across his face. Thomas, leaning against the doorframe, remained unconvinced. "We'll see, Mark," he said with a sigh. Mark just hummed happily, already picturing the tiny, colorful creature.
