Glossary

Anger is a person's emotional feeling response to a perceived threat or pain.  The expression of anger is intended to make the threat or pain go away.

To do this, animals and humans make loud sounds, bare their teeth, stare with wide open eyes, or make themselves look physically larger, for example, by waving hands around to putting hands on the hips.

These behaviors are intended to be threatening and are intended to tell the other person or animal to stop doing what they are doing and to go away now!
