“Every emotion is a result of our thoughts.”
There is no point in blaming others when we feel bad. It makes no sense at all on a practical level of reason. If we want to solve the matter constructively, we have to allow that person to understand what is going on inside of us, how we really feel.
When you accuse someone of something, the accused person has two possible choices: to take your words personally (which will make them feel hopeless and restrain them from changing their behavior) or to reject them (which won’t change their behavior either).
Apply this strategy when you feel anger.
