When you first read Harry Potter, maybe because of your age, it's easy to ignore the hidden information in the plot. Instead, you get excited when you read about a magical world and see Harry's adventures. But as you get older, you can understand it when you re-read Harry Potter. Everyone want to have magic in the dream school or place ,even there is no magic in the world,but they believe that. Rowling's characters are vivid and three-dimensional, even voldemort, the villain, is not a simple villain, he has his own complex inner world.
