First, parting is always sad. No matter what kind of separation you are, other times we are always the most sad. No matter what kind of relationship our classmates have with us, we are used to getting along with them every day. This kind of life makes us feel wonderful. But once we graduate, we have no chance to go back to another class and fight and sleep in class, so many people have too much disappointment in their hearts. Although we hated our head teacher when we were in Grade One and Grade Two, we always felt that he was too strict with us, but when we were about to leave Grade Three, we could really feel the love of our head teacher and the hope he pinned on us. We always feel that in the past three years, we have not returned anything to the class teacher, but have been making him angry, so we are reluctant to leave here.
Second, he is no longer a child. Graduation from high school also means that we are about to become adults and enter the small society of university. We are always full of fear of the future, so we can't bear to part with the present. The feelings in high school are still relatively pure. We can play well with the whole class, have our own ideas and grievances, and someone can help us. So after graduation, these students have to go their separate ways, and it is difficult for us to get together again. The friendship we once cherished most will be gone. This process is very painful.
Graduation from high school means that we won't be in the same city, and the chances of meeting each other are getting less and less year by year, and our topics are getting less and less. It means that everything we once knew should be far away from us. This feeling will make us feel helpless and sad when we think about it.
