Walking through the hustle and bustle, no matter where you and I are at this time, no matter you and I still have the integrity of life, but everyone has loved and been loved, maybe experienced unforgettable love, maybe just an ordinary life. If we can look back after we have passed, we will not remember memories. If mistakes can be corrected, there will be no sadness. If we can remember everything clearly, we will not forget it intentionally. Whether happy or sad, the story of the years repeats the same scene again and again. The timeline records every bit of life, laughter, walking, and footsteps left in life. The wind and rain wash away the clear traces, and the clear traces will gradually be lost. People in the past may no longer remember the name and appearance, only a few fragments are blurred.
