When we were young, when the teacher asked us to write the essay "My Dream", some children wrote that they wanted to be scientists, some wanted to be astronauts, doctors, lawyers, Interpol, and even supermen. Have these been achieved? I think most don't, but so what does it matter? Childhood dreams are the most sincere words from the heart. I think when you dream back at midnight and think about the cute girl who was the class president when you were a child, you will also inadvertently think of that dream you promised: Do you know? I will be a superman when I grow up. At this time, maybe you will smile. The warmth in my heart outweighs all the pain of traveling in this world.
