I have to mention the Wheel of Time series.
had Moiraine, a main character, said something beyond 'you can't understand' or avoided pretty much any and all topics during the first two books when the youngsters-to-be-heroes asked questions, about 60% of the story would have been utterly pointless and would have ended in a 'happily ever after' by book six.
"Yes Rand, you can do magic. Now let's work on those misconceptions and fears you have, instead of me brushing you off and you go on, on an angsty attempt to deny it all and run away from your problems, that ends with you killing nobles, saving nations and starting several wars (by accident and intent) before you begin to accept that you are not a sheepherder and the one you called 'father' in fact adopted you but still loves you more than life itself and that it's perfectly alright. Oh and Perrin? Yes, I know you can talk to the wolves like gazillion men before you before my order hunted them to extinction. The wolves in fact hate the Dark more than I do and are loyal allies to you. Don't worry so much. Mat? Your curiosity will kill you one day, So I'll just do us all a favour and answer your question, before you get the bright idea to run into another realm and unwittingly bargain your life away in an effort to get some answers and more than two words out of me."
