In fact, whether a person is lonely depends on his various arrangements for life. If you just pin your hopes and everything on your children. Once the child is out of our control and flies freely in the sky, we will inevitably feel lonely when we look at the back left by the child.
After middle age, we should be happy that we can finally get rid of the tedious work of caring for children. We can finally be ourselves and live for ourselves for a few more years. Do what you like.
In my imagination, when people reach middle age, I will have more time to embroider dozens of cross-stitches. You don't have to look at the time to pick up the children, you don't have to help with your homework, and you don't have to worry about your children's daily noise. My cross-stitch products will be more and more, and cross-stitch suits will be less and less. Every time you take out the finished product, you will feel full of accomplishment.
After middle age, people will feel calmer and relax and sit down and read a book they like. Share joys and sorrows with the protagonist in the book. After reading more, you will be relieved. You can use your own words to soothe your broken heart and find friends with the same hobbies in the vast online world.
When a person has a plan for his life, I think he will never feel lonely at any age.
