Anger is a passion, so it makes people feel alive and makes them feel they matter and are in charge of their lives. So people often need to renew their anger a long time after the cause of it has died, because it is a protection against helplessness and emptiness just like howling in the night. And it makes them feel less vulnerable for a little while.

Merle Shain (1935-1989) Canadian journalist and author

Hearts That We Broke Long Ago, ch. 5 (1983)
