Youth, like running water, is gone forever. As time goes by, our age is also growing slowly. How much can you remember about our wonderful life and past? For me, my most unforgettable experience is my senior three life, because the friendship at that time was so naive and really beautiful, but if I go back to senior three, I want to do too much!

First of all, now that I have entered the society, I understand the importance of academic qualifications. If I go back to senior three, I will study hard and get into a good university!

Also, if I return to the third year of high school, I will definitely confess to the girl I secretly loved at that time, so that she can understand my mind!

If I go back to senior three, I will definitely apologize to my math teacher, because I am young and frivolous and hurt my teacher's heart. At that time, I was still cocky. It's silly to think about it now!
