Many a times when we are facing those maladaptive expressions of anger (yelling or sarcasm) from others,we are not even responsible.Those people are angry at something or somebody else and we are just in the wrong place in a wrong time.We are used as proxy to unload their anger.It feels so unjust to me.If I happen to notice people who have maladaptive expressions, I run a mile from them.Not even worth it.I don't give second chances to such people.If they are family or close friends, I give them benefit of the doubt, but not for long.I go minimal contact if necessary to save myself.
