If there are feelings in this world, I think it should be three kinds of feelings. First, the feeling of classmates. Perhaps in each of our lives, the truest and purest feelings should be the campus time when we are still ignorant boys and girls. At this time, the feelings between our classmates are pure and pure. At that time, there was no interest dispute between us, and there were not many purposes to pursue. There is only a feeling that "you and I hit it off". And this kind of feeling, whether it is n years later or in the emotional waves of society, can last a lifetime. The three most authentic emotions in the world: classmates' affection, war friendship and parents' affection. Among these three kinds of feelings, the feelings between classmates should be said to be the simplest, which can last for a long time or even a lifetime. The friendship of war is the most real, endowed by life, and it is the praise and awe of life. What is more important to a person than life? And father and daughter are the most selfless and beautiful licking calves in the world! Unparalleled!
