It is a common phenomenon to get angry with relatives and be patient with strangers, which also shows people's general psychology. People are social animals. If you want to survive and move better, you need to abide by the law in the community!
Losing one's temper is a destructive behavior, and its consequence is that the relationship may break down, which means that it is not conducive to the maintenance and upgrading of community relations and is extremely unfavorable to human development! So now people have learned to control their temper.
However, people's unhappy emotions need to be vented. In order to reduce our own risks, we subconsciously choose close friends or family members to vent, because we know that these people love us, and our relationship cannot be destroyed casually, which can also improve our depressed mood. On the other hand, we have no clear understanding of strangers, including their temperament and style of doing things. If we vent our emotions casually, we are likely to suffer serious consequences. From common sense, it is very unlikely that strangers will tolerate us!
To sum up, the love of relatives and friends gives us the capital to indulge, and we can also use the word "greed".
Therefore, we should give more love and care to our families. Their angry words at the moment may just be their trust and love for you. Of course, none of us are qualified to trample on the love harbor carefully built by others for you!
