Just because you can't choose! They all say "in the moment". There are too many unfairness and disparity between the rich and the poor. Successful people are bound to fail. Saying "success" and "failure" may be too high. In addition, college students who have just left society are the most difficult "sandwich layer". They need social experience, parental protection, humiliation and many opportunities to cry! There are many things around you that may make people cry!

Besides, crying is an act of venting, which is beneficial to physical and mental health. It is even worse to be wronged for too long. You can choose not to cry in front of "grievances", which is strong, but try to cry when you get home, if you are really wronged ~
