First, there are not many friends. We'd rather have three or four sincere friends. We should be honest with each other. We don't have many fair-weather friends who only know singing and partying. Such friends are of no help to our lives. When people reach middle age, they must understand this truth and don't open their hearts to others easily. Under such circumstances, there are fewer and fewer natural friends.
Second, people don't want to socialize too much when they reach middle age. When people reach middle age, there are many social activities at work. If you are not sincere friends, you don't like going out to parties at all. Maybe it's better to be alone. Family and work have squeezed their time almost, and they have no mood to make friends everywhere. True friends are attracted, not eaten by several meals.
Third, people don't understand the importance of being alone until middle age. If you are afraid of loneliness when you are young, you often get together with friends. Then in middle age, sometimes I like someone very much. I can put aside my troubles at work and my family's disappointment and stay alone quietly. This feeling is also very good. When people reach middle age, they know their destiny and don't ask too many friends to tie them together, which makes me look down a lot.
Therefore, it is certain that there are fewer and fewer middle-aged friends. Everyone has his own work and family to be busy, and everyone has little space. If you are a family person, you will meet very few people every day. Just family and colleagues. Under such circumstances, it is difficult to make friends. The old friend also walked away.
