I have just returned from an eight-day vacation. Now I am sitting in my office with a cup of tea, but I don't feel relaxed, instead, I’m frowning. You may think that I have some difficult work to do. Actually, I am really sad because I still need to work tomorrow which means that I’ll just have a one-day weekend. So, I will have a busy schedule on the coming weekend. The only thing I really hope to do is to have a walk under the sunshine, because I haven’t seen the sun for about 10 days. We always hear some elder people say that everything can grow better with sunshine and I believe it works for human beings as we fell down when we have to do everything without sunshine. The leaves start falling off the trees while the wind blows through the trees. The thriving world starts to be silent. The bright sunshine also leaves us to go to the southern hemisphere. The wild geese also have the right to move to warm and sunny places. We can only stay here and wait them to come back soon.
