Other forms: second persons
If you're using the pronoun "you," you're speaking (or writing) in the second person. A second person statement is about the person you're addressing.
While it's unusual to read a novel written in the second person, this narrative form is commonly found in speeches, instructive writing, music lyrics, and advertising. The pronouns "you" and "your" clue you into the fact you're being addressed in the second person, whether Bruce Springsteen is singing, "You can't start a fire," or a phone book commercial is telling you to "let your fingers do the walking."
