Symon focuses. He could almost fall asleep. What is a nap, if not a mystery of time? Will you awaken in 5 minutes, or 5 hours? He wriggles a bit, enjoying the close confines - many would feel claustrophobic, like they were entombed alive, but to Symon? It's a safe space, protected on all sides, muffled from sound, snug as... well, as a worm in a hole.
He breathes slowly, shallowly, and thinks about the nature of time. To be set in stone - more so, because even stone will age, weather and crumble. As constant as the stars - even the stars will wink out and die... it's a pleasant interlude of thought towards the morbid nature of inevitable decay and entropy... but he turns his thoughts back towards time once more.
