Some people are just passing by. If you miss them, don't look back. Growth is to learn to reconcile with regrets. You thought you couldn't go on alone. But later you found that the world is still turning and the days are still moving forward. You just disappeared from other people's lives, but you still live in your own world. Let them go. You have to learn to pick yourself up and love the wind, rain, mountains, rivers, lakes and seas, and every sunrise and sunset. Because everything lost in life will eventually return in another way.
