What is the mentality of people who comment and delete?

1. I feel inappropriate: I was in a bad mood and wanted to vent. I also vented it after I sent it. Afraid of obstructing others, delete it; I was in a good mood and wanted to share it, but I felt melodramatic after posting it and deleted it.

2. Idol baggage: After talking, no one likes the comments in the circle of friends for a long time (in the sender's own opinion), or the comments fail to meet the psychological expectations, so simply delete them;

3. I want to be understood, but I am afraid of being seen: I want to share my feelings at that time, but I am very entangled. I am afraid of being seen by people I care about. I care about myself.

4. I just want to delete;

5. You can add something. . .
