Only after entering the society did I realize that a series of mental activities such as napping in class, playing on mobile phones, playing poker, chatting, reading novels, copying homework, etc., Had gone forever with my youth. This is really more sad than a sore egg. I am afraid that I will forget the days when we laughed together in the future, so I thought of writing them all down to commemorate our lost youth. Thank you for meeting you. No matter what happens in the future, please remember that no matter how awesome the years are in the future, they are not as good as the time when we were stupid together.
