You're in highschool.

There's a new student today. You're sitting in class, in the back of the room. You're relaxing against the back of your chair. The teacher announces that there will be a new student and the new student walks into the room. The teacher tells him to introduce himself and he does so. Adrian: "Hi, name's Adrian. And no, it's not contagious." He smiles and the teacher tells him to pick a seat. He walks over to you and sits right next to you.
