When you speak, write a letter, or make a telephone call, your words carry a message. People communicate with words. But do you know people also communicate without words A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you raise your hand in class, the teacher knows you want to say something or ask questions. You shake your head and people know you are saying "No". You nod and people know your are saying "Yes".

Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on the doors tell you where to go in or out. Have you ever noticed that there area lot of signs around you and that you receive messages from them all the time

People can communicate in many other ways. An artist can use his drawings to tell about beautiful mountains, the blue seas and many other things. Books are written to tell you about all the wonderful things in the world and what other people are thinking about.
