Another one

A group of young children were gathered together under the shade of a tree. At the center of the group sat a boy with light-brown hair with a book in his hands. The boy flipped the pages and read the book's contents out loud for his friends to hear. It was a storybook. 

"And then, the fox raised its front paws and put them on the tree. Opening his mouth, Mr. Fox sang a song, cough, a song with a happy face. It's tail wagging, cough cough, ahem, tail wagging, the fox waited for the, cough!"

As the light-brown-haired child at the center of the group covered his mouth and began to cough constantly, the other children sent him disapproving gazes and began to nag. 

"Arghhh why do you cough so much?"

"Yeah, I can't understand anything from the story because of you!"

"Stop coughing and read the rest!"

While the younger children complained, the older ones seized him from head to toe.

"Are you sick or something? Is that why you cough a lot?"
