C

Life is like the four seasons. Now I am very old, but when I was young, it was the spring of my life. After I was born, I played a lot, and then I started school. I learned many new things. Like a flower, I grew bigger every day. There were happy days and sorrowful days: some days the sun shone, and some days it didn’t.

In my twenties, I had a good job. I was strong and happy. Then I married and had a child. In those days, I didn’t have much time to think. Every day I was busy and worked very hard. And so, I started to get some white hairs. The summer of my life passed quickly.

Then the days got shorter. Leaves fell from the trees. My child was a university student, and then an engineer. My home was much quieter. I started walking more slowly. One day I stopped working. I had more time. I understood this was my autumn, a beautiful time when the trees change color and give us delicious fruits.

But the days kept getting shorter and colder. Winter has come. I am older and weaker. I know I do not have many days left, but I will enjoy them to the end.
