You can talk about what happened around you recently. Usually very trivial. For example, what I ate today was particularly delicious; what program I watched was particularly good; there was a boy (girl) who was particularly handsome recently; I was very lucky, I only drink three-yuan milk; I have been very busy and tired recently, and what classes are there? How is your teacher doing? Who has released a new song? How is your leader making things difficult for you? I read a very good book... The main reason is to arouse screams. As long as we are friends, there will be intersections in life. As long as we find the intersections (that is, things that both people have experienced or are experiencing, the same hobbies, the same feelings, or the same things but different feelings) ...), we can chat for a long time.
