Shiki let out a sigh of irritation, looking at the boy then the small bit of rocks. "Whatever," he said with a shrug, kneeling down before them. Examining the size a bit, he picked one up and tossed it a few times. Finally he tossed the one he was toying with out of his way and threw a punch at the bunch of rocks, shattering a few.
Shaking his fist, he picked the broken shards up and put them to his lips. With a swift tilt of his head back, he let the chunks fall to the back of his throat where he slowly swallowed them. As he finished, he peeked up at Kyuhyun over his shoulder, spitting a small pebble out that didn't seem to go down. "Well that was boring," he stood up, covering his mouth as he coughed a bit. The rocks, though smaller, were still rather sharp and had scratched at his throat as they went down.
He began walking again, "I'm hoping I don't need to ask."
