Being angry and Having anger

Anger is what we call the feeling which arises for us when we are hurt by what we perceive to be the action of another.  But being angry is not the same as having anger.  We can always bring something into our awareness about which we are angry.  The circumstance may be remote from us at the moment and thus we are not angry about it now, but it is something we may have been angry about in the past or could be angry about again.  

"Yesterday when I was driving on the highway and another car pulled right in front of me I was angry.  I am not angry about it now but when it happens again I will again be angry.  I have anger when others are not considerate of my safety."

The point of this distinction is that we always have anger even if it is not at the forefront of our emotions at the moment.
