1. comity must be measured.
Politeness has always been a virtue, but comity does not mean blindly accommodating. In life, as brothers and sisters, we are often taught to let our brothers and sisters. However, if you always let them, it won't work. For example, two children should be given half of a delicious dish, but the older children are obedient and modest, only one third is needed, and the younger children put the rest in the bowl. Parents just smile and think that older children are sensible and cute. And such things often happen, including watching TV and buying toys. After a long time, the whole family got used to it.
My brothers and sisters are getting used to this feeling of being spoiled by the whole family and gradually taking it for granted. Mom and dad, brother/sister are all humble, and the younger children are loved by thousands of people. After a long time, when eating, younger children always get themselves a big dish and plate first, without considering others at all, becoming more and more selfish.
Over time, as a brother and sister, I always feel that my parents are more and more eccentric, as if I was born the first time and was doomed to be unloved. Sometimes watching my brother/sister and parents together sweetly, no one pays attention to themselves, as if they were a family.
Parents may feel that their young children are younger and need love more, but once this kind of care is out of balance, problems will arise.
