“Listen, Dementors are among the foulest creatures to walk this earth. They feed on every good feeling, every happy memory until a person is left with nothing but his worst experiences. The Dementors affect you more than others because there are true horrors in your past, horrors your classmates can scarcely imagine. You are not weak, Harry. You have nothing to be ashamed of.”
Lupin, Prisoner of Azkaban
“A word of caution: dementors are vicious creatures. They will not distinguish between the one they hunt and the one who gets in there way. Therefore I must warn each and every one of you to give them no reason to harm you. It’s not in the nature of a dementor to be forgiving. But you know, happiness can be found even in the darkest of times, if one only remembers to turn on the light.”
Dumbledore, Prisoner of Azkaban
“It’s cruel that I got to spend so much time with James and Lily, and you so little. But know this; the ones that love us never really leave us. And you can always find them in here. [puts hand to Harry's heart]”
