In my memory, my grandfather was kind and not good at expressing himself. I never knew that he really thought. He never judged book by its cover and treated people around him equal. When I was in primary school, I sent with him a letter, telling him how much I loved him. He never mentioned that he had received the letter and I never asked. When he passed away, I cleaned out my things. I found the letter hiding in his bedroom. On the back of the letter, he writes: "I'm so glad you love me, my grandson. I love you, either." At that moment,
I was so moved that I burst into tear.
