Anger is a basic human emotion that we all feel sometimes. It is a strong sense of unhappiness and/or aggressiveness. Anger is often triggered by the feeling that you or someone else is being abused, or treated wrongly or unfairly. Imagine that you and a friend were both caught texting during class, but only you got sent to the principal’s office. The unequal punishment might make you feel angry. Different people have different triggers for anger, and different people show anger differently. Some people show their anger through physical violence, and others keep it to themselves.
