Okay, GamerDude 88, listen up. You see, the teacher says he was an orphan. The student says "That's sad." Then, the teacher asks who's away, and the student says "your parents". The student is implying that the teacher's parents are dead, hence the teacher being an orphan, which is pretty dark. It's a bit of a zing because it's not the typical answer. You were probably too busy gaming, huh?
