There are always too many memories and reluctances in life. There will always be that one person who fills your mind in an inadvertent moment. There will always be some friends who will give you enough confidence and courage when you are lost. However, the time of youth is our lingering memory, so I am looking for a place to put all my memories of youth, my thoughts of my friends, and my thoughts of her. I still vividly remember the years of high school. We were in the same classroom, at the same time, we worked hard together, struggled together, caroused together, cried together... Yes, youth is meant to be missed. When I am alone in a dark room, with only the light of the computer screen, I can't help but fall into memories, recalling my former good friends, and recalling her whom I once loved deeply. High school life is always full of fantasy, and it is worth remembering with all my heart. Later, because of an exam, we were separated from that humble classroom. However, this separation prevented many people from seeing each other again.
