Millions of people get angry every day over trifles; when this goes on and on, the mind develops a disposition for anger. It doesn't really need a reason to lose its temper; anger is its chronic state. But we should never look on angry people as inherently angry. They are simply people whose minds have been conditioned to get angry, usually because they cannot get their own way. Instead of benevolence they have developed a habit of hostility.
