Emotional expression is when people show how they feel. You know how you make different faces when you're happy, sad, or mad? That's a way of expressing your emotions. You can also express your emotions by using your voice, body, and actions. For example, if you're feeling happy, you might jump and clap your hands. If you're feeling sad, you might cry or frown. If you're feeling angry, you might stomp your feet or yell. Emotional expression is a way of letting people know how you feel so they can understand and support you. It's important to express your emotions because holding them inside for too long can make you feel even more upset.
