The small apartment felt expansive, filled with a sense of freedom, as Miles whistled while tidying. He'd rearranged the living room furniture, picturing the perfect spot for a birdcage. His roommate, Theo, was stubbornly against the idea, but Miles was certain he could eventually win him over. He was feeling a sense of anticipation that made his hands tingle.

He found himself laughing out loud, picturing the bird perched on his shoulder, chirping contentedly.

"Theo, I think this could work," he called out, his voice buoyant, when Theo walked into the room. He pointed at the spot he had in mind for the cage, already visualizing the bird there. He couldn’t wait to convince him.
