Delete chat history, text messages and online history ... what does this mean? (Please use fewer terms and be more specific, thank you _) y)

I think this kind of behavior has a certain sense of self-protection on the surface, but it is essentially a manifestation of lack of confidence in one's life. My younger brother is not deeply involved in the WTO and does not have a deep study of people's psychological activities. However, I think people are just like computers. What they have experienced recently will naturally be stored in the cache for a period of time, and then cleaned up regularly. If a person has the habit mentioned by the landlord, it can be seen that he lacks a sense of security in his daily life and is worried about the clues left by his various minutes meetings, which will have a negative impact on himself. As a normal person, he should also properly handle his life records and deal with all this confidently.

However, people are different after all, and we should not use our own standards to measure other people's behavior. I also wish this friend and his friends a happy life.
