Introduction to Letters to Sam
Dear Reader,
Please allow me to tell you something before you read this book. When my1, Sam, was born, my heart was filled with joy. I had been sitting in a wheelchair for 20 years before then, and I have been2ill many times. So I wondered if I would have the3to tell Sam what I had4.
For years I have been hosting a program on the5and writing articles for a magazine.  Being6to move freely, I have learned to sit still and keep my heart7, exchanging thoughts with thousands of listeners and8. So when Sam was born, I9to tell him about school and friendship, romance and work, love and everything else. That's how I started to write these10. I hope that Sam would11them sooner or later.
However, that expectation12when Sam showed signs of autism (自闭症) at the age of two. He had actually stopped talking before the discovery of the signs. He13to communicate with others, even the family members. That was14for me but didn't stop me writing on. I realized that I had even15now to tell him. I wanted him to16what it means to be "different" from others, and learn how to fight against the misfortune he'll17as I myself, his grandfather, did. I just18if I could write all that I wanted to say in the rest of my life.
Now,19the book has been published, I have been given the chance. Every chapter in the book is a letter to Sam: some about my life, and all about what it means to be a20.
