The Sphinx by the Pool

Arthur stood by the empty swimming pool, its concrete cracked and weathered, much like himself. At seventy-eight, he'd learned that time erodes everything eventually — even the places that once felt eternal.

"Grandpa?" Emma's voice pulled him back. "You okay?"

He smiled at his granddaughter, wearing a zombie costume she'd begged him to buy. Halloween approached, and somehow he'd become her accomplice.

"Just remembering," he said. "This is where I met your great-uncle Marcus. We were twelve. He challenged me to a race across this pool."

"Who won?"

"He did. But I gained a friend for sixty-six years." Arthur's voice softened. "Marcus was like a sphinx — always asking riddles, never giving straight answers. 'What's worth more than gold but can't be bought?' he'd ask me on this very deck. I spent years figuring out his answer."

Emma took his hand, her zombie makeup smudged. "What was it?"

"Time." Arthur squeezed her fingers. "And the people who spend it with you."

They walked to his car, a teddy bear from Emma's childhood buckled into the back seat — a silly thing he'd refused to throw away. Some treasures didn't make sense to others.

"Grandpa," she said suddenly, "when you're really old, don't become one of those zombies who just sits and watches TV all day. Promise?"

Arthur laughed, a warm sound that surprised even him. "I promise, kiddo. I've got too many stories left to tell. Too many riddles left to solve."

That evening, he called his sister. "Sarah, remember what Marcus taught us? About bearing witness to each other's lives?"

"I remember," she said. "Why?"

"Because today," Arthur said, looking at the zombie mask on his kitchen table, "I realized that's how we defeat the walking dead part of getting old. We keep showing up for each other."

Sarah's voice came through warm and steady. "Marcus would be proud. You finally learned his best riddle."

Arthur smiled. Some answers, like some friendships, only deepened with time.
