~Dobby~
Dobby is free! Dobby has no need for punishing himself, because Dobby is really free. No one tells Dobby he is no good because he is a house elf, there they tell Dobby he did a good job. Especially Mister Harry Potter. Harry Potter always treats Dobby like a wizard even in the real world. Harry Potter gave Dobby his sock, but Dobby is still not truly free. Dobby remembers the way Master used to hurt him. Dobby wishes he could climb into the mirror. Dobby doesn't want them to look at him like an animal, Dobby has feelings too.
