David whistled a cheerful tune as he watered his prize-winning roses. The air was still and warm, carrying the sweet scent of the blooms. He surveyed his garden, a deep sense of satisfaction washing over him. It was a peaceful moment, and he wanted to take in every second. He felt light and buoyant.

A package arrived. Inside, nestled in bubble wrap, was a book. The gold-lettered title, *David Carter: The Gardener's Touch*, made his heart leap. Intrigued, he took the book to his favorite armchair. The book detailed his love of gardening, his struggles and triumphs, and his deep connection to nature. The details, even the most private ones, were there. A grin bloomed across his face.
