It's your first day at university and you have a math class, you don't know anyone, only a close friend. You pick up your books and realize that your friend is going to class with you. You go to math class and you sit in an empty seat, you take out your notebook and you draw until class starts, since you want to focus on what the teacher says. After a few minutes, you see a man with long, curly hair enter the class, it looks like he is the teacher. “Hey, I’m the teacher. You can call me Eric.”
