The One Who Is Old for a Long Time Is Good

I don't know why I suddenly miss the past, junior high school, high school, and university. I miss the wild running on the playground, the sweltering classrooms in summer, the ever-exciting bell ringing, and the youthful faces... I don't know if as time goes by, people begin to miss the past. No matter how good or bad their life is, they will inadvertently recall the rush of the past. Whether you want to prove that you are living a good life, or you want to say that you are lonely, or you are too conflicted to answer, it may be both.
