The second principle is laziness. We just want to make friends with people close to us, such as colleagues in the company. If we get close, we will get to know each other. If we leave, we will become estranged. When we combine these two principles, it is easy to fall into an interpersonal trap.
When the social circle narrows, we only like to associate with people who like us and can't see the real world, so we should learn to break the interpersonal trap.
