Sometimes it’s road rage. In one case it was a customer at a fast food restaurant throwing a burger at a cashier when he discovered they’d forgotten to add the pickles. What triggers the proverbial "straw that breaks the camel’s back?"
Why do adults throw tantrums over small provocations? Shouldn’t we have learned from childhood that indulging in a fit of yelling, whether at a customer-service rep or a spouse, never helps? In fact, sometimes these actions hurt OURSELVES, since they alienate the people who are supposed to help us.
Contrary to popular opinion, it’s not always helpful to express your anger. Another new discovery is that some people actually ENCOURAGE other people to get angry at them because they find it rewarding.
