When we stand up after falling, we learn to be strong; when we wash our dirty clothes, we learn to be self-reliant; when we make a cup of tea for our parents, we learn to be filial... when we learn to do this, we grow up, and grow up again and again, we will eventually be president. Big. After that time, I learned to persist. That day, the teacher asked us to type our composition in the computer, and print it out, and hand it in the next day. So I spent ten minutes typing my composition on the computer. As I moved out of the USB drive, it occurred to me that my printer had lost ink and that the new cartridge had just arrived. I immediately decided to print the shop. I copy the composition in the U disk. But looked out of the window. There was a heavy rain outside the window, and the wind was blowing. I thought to myself: If it hadn't rained so hard, I would have explained it to my teacher tomorrow, and some of my classmates would have missed it. But I thought again: what would the teacher think if I didn't finish this assignment today? I hesitated for a long time and still thought it would be better to print. I took out my umbrella, walked out of my house and walked towards the printing shop. It was hard to get to the print shop, and the boss opened the U disk, resulting in a bunch of garbled code. The printer gave me my USB drive back, told me to come back when I had it ready at home, and told me to hurry up and the printer shop closed at 8 o'clock on time. I had to go home again in a storm. Back home, just opened the computer, but found that the computer is updated automatically, can not be used. I thought to myself: I was unlucky. First of all, the weather was so bad that the computer was going to be updated again. God didn't help me.. I had to knock on my neighbor's door and borrow my computer. Aunt is very generous to lend me the computer. I quickly found the problem, changed it, saved it, and prepared to go to the print shop again. Aunt said, "It's 8 o'clock. You're going to the printer's shop, right. I'll just print it for you. The printer we just bought is still in use." I thought to myself, "there is no way out." So I gave the U tray to my auntie, and my aunt quickly typed it for me, and gave me the paper and the U tray. It was already half past nine when I got home. In retrospect, I would shrink back if I met with a little difficulty, but now, I have been able to overcome the difficulties and learn to persist! I am grown up!
