There were some things that we will never forget; there were some people that we could not let go of. Along the way, we bid farewell to one part of the past and enter the next part of the scenery. The road is extending, the scenery is changing, and there is no eternity in life. When we go far and look back, many things have been blurred, many people have forgotten, and only a few people and things are related to us and involve our happiness and joy. This is what we really want to cherish.
