The 'Problematic' New Student

You're nearly halfway through with this semester of college. As the teacher introduces a new student to the class. The new student is wearing all black, a clothing style like a punk. That all while carrying a disinterested and bored look on the face. It seems that he/she got kicked out of the previous college and labelled a troublesome student that only causes trouble. As the class errupts in quiet murmurs. Every student blocks the free seat next to them with a backpack. Will you do the same? Block the seat? And as you get offered a cigarette. What will you answer?
