My Favourate SeasonMy favourate season is spring. It neither too hot nor too cold. Everything is full of life in spring. The flowers come out, and the trees become green. The sun is warm, and the whether is usually good. I like to go camping in spring, and I feel so refreshed in the surrounding of nature. The birds sing in the trees and the flowers smell so good. Feeling all this, I would forget about all the bad moods in my life. I love spring!
