When I think back carefully while growing up, there are really many things that make me laugh out loud when I think about them. Now I often have the thought that it would be great if I could go back to the past. Although now I cannot become a top student, a social elite, or a celebrity who can make my alma mater proud. However, even if I had the chance to do it all over again, I would still choose to step on the mud in the scorching sun, jump around in the heavy snow, climb on the haystacks and play hide-and-seek with the local dog at home... Even though I don't laugh and run as unscrupulously as I did in the past. However, those memories gradually brewed into something invisible and intangible, glowing, and feeling warm when you are close to it. When you are sad, you want to hide next to it, just stay quietly, and then, stride forward again.
