i love to read because I can wrap myself in the security of someone else's story i can envelop myself in the warmth of the characters who become friends and when the book ends i feel saudade a nostalgic longing to be near again to something or someone that is distant, or that has been loved and then lost; "The love that remains" and that is the best fit definition i could find because that feeling feels so indescribable but characters become so real they become friends and family and you can't help but feel after the story is over *and then the process repeats.
