Next year is the year of the sheep. According to East Asian ideas, people who are born in this year are polite, clever and cautious. They look after their parents and enjoy a quiet lifestyle. Of course, they have their weak points. They tend to worry and cannot make decisions. In English-speaking cultures, we don’t have a good image of sheep. We see them as animals that cannot think or lead. All they can do is follow. Of course, we like their wool and their meat, but no one wants to be called a sheep. (by Prof. Douglas Jarrell)
