:mrgreen: After reading everybody elses posts, i think its all of them. Like lily and james' life before harry, and everyone around him who is a wizard, and things like that. I think he probably didn't tell him til now because an 11 yr old prolly couldn't handle all of the info he would give him (also to keep the reader in suspense). Like in the first book when he was dropped off at the Dursley's Dumbdore said that his fame would be too much for him at to young an age.
