New Rowling Interview
Harryahistory got in an interview with Rowling. Below you can read an excerpt.

JKR: "I think it makes Dumbledore a little less culpable.

That's what I saw as Dumbledore's past. That's always what I saw was in his past. And he keeps a distance between himself and others through humour, a certain detachment and a frivolity of manner.
