There are many reasons, such as time, emotion, place, money and even social status. I think they are all reasons for staying away from class reunion.
However, middle-aged people have great responsibilities. Many people will use their spare time to earn some extra money and go out for class reunion, which is an unnecessary extra expense for some people. Moreover, we have been apart for a long time, and have experienced many experiences that the other party has never had, and there are fewer topics to talk about together. The so-called class reunion sometimes just becomes a dinner party for several people in the family. Sometimes I go to class reunion with great hope, but I am disappointed and even ruin my good feelings for others. Without that reunion, we sometimes chatted from time to time. Maybe because of that reunion, we really parted ways. After all, the world of adults is full of unspeakable suffering and quite complicated.
The previous reunion was right, but it should also be selective and get together with people who feel happy and miss each other. It was the best reunion for classmates. Don't care how many people there are, just care about sincerity.
