His mind wandered, back to his old home, to his grandmother's cat, a calico named Patches, and the feel of the cat’s gentle purr against his ear while he did homework. It felt like another lifetime.

He took a slow, deep breath, running a hand through his hair, a gesture he had often done back then, too. "I… I just don't think I can," he said, the words barely a whisper. The idea of getting a cat, of sharing his small space with another living being, just felt… wrong.
