“A word of caution: dementors are vicious creatures. They will not distinguish between the one they hunt and the one who gets in their 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…”— Steve Kloves, Albus Dumbledore, Michael Gambon, imdb.com
“The worst thing about prison was the dementors.”— Ricky Gervais, Stephen Merchant, Michael Scott, Steve Carell, amazon.com
