On a cold Sunday, a strong wind blew in the morning and it rained heavily. Rain fell from the sky and dripped on the window, as if to break our window, and kept making a snapping sound.

Suddenly, someone rang my doorbell, and I hid under the thick bed and thought, who is it? Ring my doorbell so early. I looked out of the window and saw a man carrying a green backpack with a big letter written on it. "Ah, uncle is the postman. Why did he deliver the newspaper so early? This made me sleep very badly. " I went downstairs to open the door in a thick cotton-padded jacket. I saw uncle postman's clothes all wet, so I cared? Uncle postman, why don't you come in and deliver the letter? "No" "Uncle postman, let me lend you a water jacket." "No, I have, thank you." With that, he took out a letter from his backpack and gave it to me, and left. I looked at it carefully before I saw the water jacket covered in the newspaper. Suddenly, my heart was very excited.

Ah! It is these unknown postmen who bring us convenience!
