But I think we should look at this sentence again.
"Talk to people when you meet them", and you can communicate with people.
You can communicate with ghosts by talking nonsense.
If you talk nonsense when you meet people, it won't work.
Therefore, "lying to everyone" is a secret of communication, and it is also a secret of getting along with people, making friends, giving people a good image and getting to know each other. This is a skill, an art, flashy, opportunistic and insincere?
The main meaning of this sentence is: you should try to talk about familiar and happy topics in a language that the other person can agree with!
In fact, it is very useful to talk nonsense when you meet people. The great thing is that if you grasp the weakness that people tend to be self-centered and let the other person's self be satisfied in language, the other person's defense consciousness will soften, and you may "care" (be polite and kind to him) and have a good impression on you. As a result, you know him for three or four points, and he may know nothing about you!
