How are you greeted? What do they have for breakfast? And what do children from all over the world do when a tooth falls out? From citizens of huge countries to tiny African tribes, we all eat, dress, play and believe in omens. "Welcome to our world" can inspire a child to learn languages, travel, find friends among representatives of other cultures, and, most importantly, help to feel a part of a large and diverse world in which people treat each other with curiosity and sympathy.
