When you are alone, you will gain some insights into life, think about this and that. When I was young, I didn't understand what adults said, couldn't understand, and didn't take it seriously. As I grew up, I gradually understood it, but found that many things were contradictory and I didn't know how to choose. There are some things that I think about how to face, but always choose to escape. Run away as long as you can, face it only when you have nowhere to run, and sigh after you solve it. It's not that difficult! Just smile and it will pass.
