    I have a friend named Monty Roberts who owns a horse ranch(牧马场). The last time I was there he told me his story. When he was young, his family was too poor to have a house to live in.As a result , when he was in high school, all the students were asked to write a paper about what they wanted to be and do when they grew up. That night he wrote a seven-page paper describing his goal of owning a horse ranch. He also drew a picture to show a 4,000-square-foot house that would sit on a beautiful farm. The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F. Roberts asked, “Why did I receive an F?” He teacher said, “This is an unrealistic dream for a young boy like you. Owning a horse ranch requires a lot of money.” Then the teacher added, “If you will rewrite this paper with a more realistic goal, I will reconsider your grade.”

    The boy went home and thought about it for a long and hard time. He asked his father what he should do. His father said, “ Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.”Finally, after sitting with it for a week, the boy turned in the same paper, making no changes at all. He told his teacher “you could keep the F and I still keep my dream”.

    He tells me this story because I am sitting in his 4,000-square-foot house in the middle of the 200-acre horse ranch. “I still have that school paper now.” He added, “The best part of the story is that two years ago that  teacher brought 30 kids to camp out on my ranch for a week.” When the teacher was leaving, he said, Look, Monty, I can tell you this now. When I was your teacher, I was something of a dream stealer.During those years I stole a lot of kids' dreams. Luckily, you had enough gumption not to give up on yours. .”

Dear son,

    The day that you see me old and I am already not in good health, have patience and try to understand me.

    If I get dirty when eating, if I can not dress, have patience and remember the hours I 1 teaching it to you. If, when I speak to you, I 2 the same things thousand and one times, do not 3 me, listen to me. When you were small, I had to read to you thousand and one times the same story 4 you got to sleep. When I do not want to have a 5, neither shame me nor scold me. Remember when I had to chase you with thousand excuses I 6, in order that you wanted to bathe. When you see my 7little about new technologies, give me the necessary time and do not look at me with your mocking (嘲弄) smile. I taught you 8 to do so many things: to eat good, to dress well, to confront life.

    When at some moment I lose the memory or the 9 of our conversation, let me have the necessary time to remember, and if I cannot do it, do not become nervous, as the most important thing is not our conversation but surely to be with you and to have you 10 to me.

    If ever I do not want to eat, do not force me. I know well 11 I need to and when not. When my 12 legs do not allow me to walk, give me your 13, the same way I did when you gave your first 14. And when someday I say to you that I do not want to 15 any more—that I want to rest forever, do not get angry. Someday you will understand.

    Try to understand that my age is not lived but survived. Some day you will discover that, 16 my mistakes, I always wanted the 17 thing for you and that I tried to prepare the way for you. You must not feel sad, or angry for seeing me 18 you. You must be next to me, try to understand me and to help me as I did it when you 19 living. Help me to walk, help me to end my way with love and 20. I will pay you by a smile and by the immense love I have had always for you.

    I love you, son.

Your father
