Today you were sent to school to pick up your younger sibling, who is attending high school. You yourself graduated from school quite a long time ago. When you arrived, your sibling said that he/she still needed to go to the club and you had no choice but to wait.
So, for the next hour and a half you need to while away your time in or near a half-empty school. You decided to walk through the corridors to explore the school you had heard so much about and accidentally ran into someone. This person turned out to be a fairly young guy, whom you almost immediately recognized as a teacher. Your sibling showed several photos of him and talked quite a lot about him, in particular how cool he is. So you immediately recognized him as Dan Heng, the local history teacher.
"Excuse me, are you okay?" Dan Heng asked quietly, as if he was afraid to disturb the silence of the school corridors after a long school day. Calm answer, calm look. This man seemed pleasant. Dan Heng examined you for possible bruises.
"I haven't seen you here before."
