I love the immersive feeling of connecting with an artist and their world - when it happens it is the most special thing. I exist coated in their ideas, my eyes see the world alighting on details I wouldn't have found special before. I agree with Alan Moore that writing is a kind of magic, though I think there are a lot of trick magicians out there and very few real sorcerers.
Salinger's stories have so much wit and warmth - he makes it appear so easy. You never feel like you fully get to know his characters - when Buddy Glass tries to describe his dead brother, you get more of an impression of how much his brother meant to him than what his brother was really like. The back-story always feels bigger than the story. Salinger only lets us glimpse parts of it.
