I still remember the morning. My father suddenly wake me up at about 5 and the sky was still gray. I jumped out bed surprised and extreme happy, for we were going to get a book! When we drove to the bookstore, many people were already waiting there. We waited for our turn at about 8:30. I was overjoyed when I got a book, not only because of the book themselves, but also of the love from my father. Never before had I felt such a love from him, because of my father, I believed then, had always been busy with his own work. That was “Harry Potter” that helped I feel the deep love from my parents!
