There are three kinds: either he is older than 80, thinks he is playing 80 and doesn't want to talk to people younger than himself, which is the least likely. Then the post-80s are generally in contact with their peers, and they don't want to communicate with their peers, which is more likely. Then he is younger than 80 or 90, or zero has grown up in the shadow of the "beat generation" after 80 in their world view. It is a very unpleasant thing to be inherited this label that should not belong to them. If this is nothing, then the most fatal thing is that the independent, narcissistic and unrestrained post-90 s and post-00 s are also criticized and dissatisfied by the post-80 s who they think are the least qualified to preach, and gradually enter 30 years old. Of course, this possibility is indeed much higher than the first two, but they are pursuing one. In this era of personality, in order to attract the attention of others, it is the greatest skill and the most demanding. It is hard to say that this is not using the role of "unconscious recording" in psychology. The more I hope to attract the post-80s generation, the more I hope they will stay away from other age groups. Only the rejected post-80s will be moved by their urgent hopes. Why are they excluded or the landlord won't ask me if I'm right?
