No matter how lucky or unfortunate life is, it is all in the past, just like the rain outside the window, which has been soaked, wet, gone and far away. Once beautiful, stay in my heart, once sad, put it behind me, learn to forget, know how to give up, and life always moves from farewell to tomorrow. Tell yourself quietly, it's okay, everything is like this, long life, indifferent treatment, everything will pass, and the sunshine will always be after the storm.
