Once in a while, I saw a picture full of villains, with a line on the picture: My commander is dead, no, my commander has grown up.

Oh, yes! They've all grown up! Looking back, in my good youth, I didn't do anything vigorous, but my life was dull and I left too many regrets. I often envied Doraemon's time machine when I was a child, and I still yearn for it. I want to go back in time and say to that girl I used to have, I like you. I want to go back in time and say to me when I was a child, I must study hard. I want to go back in time and catch my father the moment he falls..... It's all just imagination.

The black hair does not know how to study early, and the white head regrets studying late. When I was in middle school, I was often called a parent, and the teacher kept saying that this child was too stupid to learn at all..... My parents may have been accustomed to this set of rhetoric and did not tell me much about learning. But I don't want to! Whenever I go to class, all I have in my mind is something interesting or a movie clip. I kept trying to listen, but in the end, I still didn't know anything. When I took the exam, I had to rely on my own luck to get the answers, and sometimes my luck would be very good, and when the overall performance of the class declined, I could guarantee a score of 60, but for most of the exams, I was always the first and second, of course, the last.

When I was in college, I often saw many people in order to pursue a certain girl, in the school playground full of candles, boldly confessed to her, at that time, we only knew to laugh at them stupidly: if the girl refused, see how he got off the stage. The storyline often doesn't go the way I hoped, and in the end, you can only see the two embracing each other, and we are suffering a huge single injury. These things also came to my mind, but I didn't meet the person at that age who wanted to do all this for her the most.

In the good youth, there is nothing more worrying about than parents. The children have grown up and can't control them anymore, at this time, everyone also ignores the feelings of their parents, for their dreams and those so-called loves, they only remember what their girlfriends like, what they like to eat, and even forget when their parents' birthdays are.

After graduation, everyone got busy and rarely got together together, but every time they got together, there would be one more newlyweds and one less single person. Everyone laughed and talked about the miserable life after marriage, and thought of themselves many years ago, lamenting the passage of time.

Time returned to many years ago, on the White Deer Plain, there were a few fledgling children, riding mountain bikes under the sunset, shouting at the sunset, long live youth.

Youth is spent in confusion, everyone has changed a lot, it is no longer the teenager it used to be, a group of people stood under the sunset and shouted: Youth! Good bye!

Youth! Never again!
