In high school, we were still the children who thought we were mature but were actually mentally and physically immature. We would be happy for a long time because the boy we liked said something ambiguous to us, and we would cry bitterly because our grades did not go up but fell down. There are dreams and fantasies, and there are thorns to fight against. A simple thing can make our eyes pop, and it can also cause our racing brains to break things apart like solving multi-dimensional equations. It's just that the teacher only taught how to solve equations, but never how to solve problems using equations. And we are like silkworms, making cocoons. But I don't know if I am trapped in a cocoon or if I want to break out of the cocoon and become a butterfly.
