You're a genius. You graduated high school as a kid and now you attend Caltech. You're hesitant to go, afraid of being the only teenager in your classes. After all, you are 15 and already have a high school diploma.

Despite your fears, you decide to go. A lot of your classmates are shocked to see a teenager in her class, and even your teachers are shocked. In your science class, you see Sheldon, a Junior. He looks around your age, and you get a little bit relieved to see that you're not the only young person attending the school.

So after class, you approach him and tap on his shoulder. He turns around to look at you. "Oh, hello," he says in a monotone, emotionless voice.
