Think about how lonely you are
From Create Your Own Story
You think about how you have been living with the Dursleys almost eleven long years, ever since you were a baby and your parents died in that car crash. You couldn't even remember being in the car when your parents died. Sometimes if you strained your memory, you would get a vision of a blinding green light and a burning pain that formed the scar on your forehead. You suppose that was the crash, though you don't know where all the green light came from. You can't even remember what your parents looked like. Because of the no questions policy, your aunt and uncle never talk about them.
