David found himself staring out at the garden, now overgrown, a pale imitation of its former self. He remembered the vibrant sunflowers they had planted together, their golden faces reaching for the sun. The scent of roses, the gentle hum of bees.

He’d always associated that garden with Sarah, his sister. It was a time of shared laughter, quiet companionship, and shared hopes for the future. He could still vividly recall the day they had buried a time capsule, a secret buried deep.

Sarah had been visiting last weekend, and the conversation steered towards the capsule. To David's surprise, she claimed *he* had been the one who wanted to bury it. He had always been the skeptic, while she was the dreamer.

He walked outside, the air heavy with an emotion he couldn't name, and the memory of the garden, once so crystal clear, seemed to shift slightly with every gust of wind.
