Borrow the office, look at the picture and write how to write.

One day, Xiaojun borrowed a joke from the library. He likes it so much that he even watches it while walking.

Walking, he saw a particularly funny joke. He smiled: "Ha ha ha ..." At this moment, a librarian came. She pointed to the big word "quiet" on the wall and said, "Children, please don't laugh in the library!" Xiaojun woke up at this time. He quickly said, "I'm sorry, I didn't mean to." With that, he ran out of the library with a smile.

After coming out, he finally burst into laughter again.
