At the beginning of life, when friends are young, when they reach a certain age, they will be separated and have good economic conditions. Then they feel that they can't catch up with each other, and gradually find that the worst thing they have ever seen is themselves, so sometimes they don't want to walk around.
In your heart, I feel that all your friends are excellent. They are all running fast in the car, only you are walking slowly, and you can't catch up if you want to. They left without informing you or helping you.
Maybe you have encountered difficulties in your life and want your friends around you to help you, but they didn't help you, and you feel helpless.
