Social etiquette is self-taught without learning. Do you agree? Please give your reasons.

I don't agree. It is true that we can learn some manners without learning them, but this is what we will do only after being subtly influenced. Etiquette plays a positive role in regulating people's social behavior, coordinating interpersonal relationships and promoting the development of human society. Etiquette is established in people's life and social communication. People can correctly grasp the scale of interpersonal communication with the outside world and handle the relationship between good people reasonably according to various etiquette norms. Without these etiquette norms, people will often feel at a loss in communication, and even be rude to others and make jokes. Therefore, if you are familiar with and master etiquette, you can do it by analogy and treat people just right. As the saying goes, "When we have a threesome, we must learn from others." When we see others go to social etiquette, it is actually a learning process. Although others don't teach it in person, we learn from them. Sometimes others tell us that what we can do is also a learning process. Whether it is a teacher in class or a parent, a friend or a colleague or even a stranger in life, it is a teacher who teaches us social etiquette.
