Standing on the tail of time, looking at the past, it turns out that we have forgotten too much, maybe it is because time is gone. The past can never come back, why should we hold on to it tightly? In fact, giving up is also a kind of gain. Only by giving up the hope of being tearful and empty can we gain more hope. When the leaves leave the tree, is it the tree's unwillingness to retain it, or is it the pursuit of the wind? Many years later, when we recall the present momentarily or casually, will we seriously count our tears, our laughter, our happiness, our sadness, our encounters, our togetherness and our separate ways? If one day, everything can go back and go to the end of the sky, where we can find everything we lost and find the scene where we parted after so many years, will we choose that we never met, and there were not so many smiles and so many tears. I would like to write this article to commemorate my three years of junior high school. Those more than a thousand days will be my eternal memory.
