Sam headed down the stairs, and paused as he spotted two other students heading up. He recognized them as Jon and Karyn...he hadn't known either of them till earlier today, and he was reasonably certain that they didn't know him.
It wasn't as if he was particularly memorable. He was average and nondescript, with messy brown hair and looked like many other students, including Jon himself.
"Hey, Sam," Jon said as they passed.
He looked at Jon. Jon was dressed differently...like he'd noticed several people were, and suddenly had long red hair. He panicked, wondering if Jon knew what was going on, and ran off.
He ran down the stairs and out a side door to the street, out of breath, feeling dizzy, and picked the stone out of his pocket. It was flashing intermittently, like the hard drive light on a computer. But he didn't understand what was going on. He hadn't wished for the school to get taller, or for any of the things he'd seen starting to happen. He'd just wished for...
He paused, losing his train of thought as he felt something strange. It felt like a very subtle stretching. He looked down...his legs were getting longer. He dropped the stone back into his bag with fingers that had been a bit stubby, growing long, and somewhat artistic looking.
He slumped against the wall, not actually in physical pain but not quite knowing how to control his changing body, moaning softly.
