First of all, the older generation thinks it is their responsibility to educate the younger generation. Therefore, they will think that if they don't pass on their knowledge and experience to the younger generation, it is a sign of dereliction of duty, so they will appear to be "good teachers."

Second, education has also given the older generation a possible sense of accomplishment. By educating the younger generation, after the younger generation has repeatedly avoided losses or achieved some achievements, the older generation has gained a sense of satisfaction and accomplishment. The common phenomenon of children's comparison is the embodiment of this psychology to some extent, or in other words, it can be called vanity.

Third, educating the younger generation is a kind of self-salvation and self-improvement. The older generation has accumulated some experiences and lessons, hoping that young people will not make mistakes and suffer losses on the same thing, and that the younger generation will accelerate their success and take fewer detours.

Fourth, educating the younger generation can show their identity. Influenced by some ideologies and concepts, some people of the older generation will gain a sense of existence and control through education.

Fifth, educating the younger generation may also be a sign of love that adults think. Education is a social activity to cultivate people consciously, in which family education and school education are basically the education of the older generation to the younger generation. Whether parents treat their children or teachers treat their students, they are essentially manifestations of love.
