This sentence can be used to describe the journey of life and interpersonal relationships. In the journey of life, we often meet all kinds of scenery, some of which may surprise us, some may make us feel calm, and some may make us feel shocked. However, these landscapes can only be seen during our journey, and once we reach our destination, they may not be so attractive.
Similarly, the emotional connection we establish with people may not be superficial communication. Some people may not be our friends, but they may give us help and support at some time. These people may not always accompany us, but their emotional support may appear when we need it most and stay in our hearts deeply.
So this sentence reminds us to cherish every moment of our journey and not to ignore those people and things that may bring us a profound emotional experience.
