There are all types of different people. All people look different, even twins! I have a twin sister, and you can tell, we look sort of different, but it is hard to notice. There are people form all around the world, and, they all speak differently, in different languages, and accents. Some people have higher voices, some people have lower voices. There are about 7,038,044,500 people in the entire world. But, not a single person looks or speaks alike.
