Arthur, a man of routine and habit, had been dreading the inevitable announcement. When the condo conversion notice finally appeared, however, a surprising sensation washed over him. He felt… buoyant? He wasn't sure. His usual morning routine, usually a slow, deliberate trudge, now felt like a brisk march.

He tackled tasks he had been putting off for years. He repaired the leaky faucet, fixed the wobbly chair, and even started painting the hallway a cheerful shade of blue. He began to organize his vast collection of books.

He spent the evening listening to his old vinyl records, the music filling the apartment with a vibrant energy that matched his mood. He felt like he could stay up all night.
