Describe grandpa's writing style. How to write it?

My dear grandpa.

I have a very lovely grandfather, who is my relative and my friend. He retired, and now he often stays at home with me. Every time I see grandpa's smiling face, I feel that life is full of hope and happiness.

Grandpa is a very diligent person. He loved studying and working very much since he was a child. When he was young, he worked as a technical engineer in a factory. He not only performed well in his work, but also contributed to the local education as an educator.

Now, although grandpa has retired, he still works and studies very hard. Every morning, he gets up and goes to the gym to exercise to keep healthy and energetic. Then, he will go home and grow his own flowers and vegetables, and send fresh vegetables and flowers to his family and neighbors. In the evening, he will study and constantly enrich his knowledge and skills. He often tells me that only by continuous learning and progress can we remain young and energetic.

Grandpa is not only a hardworking person, but also a very caring person. He always cares about me and loves me very much. He has been my closest companion and friend since childhood. Whenever I encounter difficulties and setbacks, he always encourages me, supports me and gives me help and advice. He often plays games, watches movies and discusses current events with me, which makes me feel very happy and full.

What moved me most was that Grandpa still had a kind heart. He often donates money to charities and does his part for those in need. He said that only by helping others can we make ourselves happier and more satisfied.

My grandfather is a very lovely, hardworking, caring and kind person. He is not only my relative, but also my good friend. I am very grateful to have such a grandfather, who let me learn a lot of knowledge and truth in the process of growing up, and also let me feel the warmth and happiness of my family. I love my grandfather, and I wish him health, happiness and happiness forever! In the process of growing up, I deeply realized that a person needs not only the qualities of diligence, kindness and intelligence, but also the qualities of love, patience and understanding. These qualities are perfectly reflected in my grandfather.

In my mind, grandpa is a great man. He used his words and deeds to interpret a person's quality and spirit. He set an example for me and made me feel the warmth of my family and the beauty of mankind. I will inherit his spirit and work hard for the beauty and happiness of mankind.

Thank grandpa for everything he has brought me. I love him and wish him happiness forever!
