In spring, the weather changes a lot. In the morning, when I took bus to school, the weather was breezy and comfortable. I thought it would be a great day. However, when I got to school, the sky turned to be gray with the gloomy clouds as well as thunder. After a little while, it started to rain heavily. I was worried because I didn't take my umbrella. I was afraid that I can’t go home after class. About thirty minutes later, the rain stopped and it was sunny before long. The air was so fresh and the sky was clear. This is spring.
