Because you don't understand, you make mistakes; because you are stubborn, you are crazy. In our young and frivolous years, we were afraid of being alone and longed for friends. We also had our first love, but we often failed our loved ones who loved us the most. When we grow up a little, we suddenly look back and realize that every emotion in the world is worth cherishing, and the kindness of our parents cannot be repaid. There is no youth without pain, and there is no life without pain. It hurts, but I understand.
