Chenglei pulled his hand back and swallowed hard, trying to move past this while he looked for his time table, which was folded up and slightly creasy in his pocket. He handed that over, because now he was in this interaction, and then replied. "I'm Zhou Chenglei." And this guy had a bit of a strange way of talking. Or maybe that was just because he'd weirded him out with the hand thing, he could see that. "I moved."

That was about as far as he'd gotten with thinking up a reason for why he started school here mid-year.
