He sat on the park bench, hunched over, the patent rejection letter clutched tightly in his fist. The words swam before his eyes: "Prior Art." His portable language translator, the thing he'd envisioned helping people connect across borders, was already out there. Someone else, with deeper pockets and faster access, had stolen his thunder.

The vibrant colors of the autumn leaves seemed to mock his dejection. The laughter of children playing nearby grated on his nerves. He felt a hollowness in his chest, a deep ache that refused to be ignored.

"Just a waste," he muttered, the words barely audible. His invention had been his everything. Now, the project felt like ashes in his mouth.

He stood up, shoving the letter into his pocket, and started to walk, but the joy he usually found in his stroll was gone, replaced by a lingering gloom.
