Susan was doing her homework in her room when her father came in. "Do you need help?" Dad asked. "It's almost bedtime. " "No, thanks," Susan replied. "All I have to do is to paint a rose. " However, when she was about to finish, she dropped the brush on the picture! There was a blob (污点) in the middle of her picture.

"No, no, no!" Susan cried. "My rose!" The picture looked like a mess! "Oh, relax. " Dad said. "That blob in the middle can be anything. Maybe a spot (斑点) on a bird or a cat. Just be creative. "

"Yes, that's right!" said Susan. "Thanks, Dad. You just saved the day!" She picked up her paintbrush again, and soon the blob on her picture became a spot on a cute little butterfly. She then added more butterflies to her picture.

The next afternoon came the art class. Mr. King, the art teacher, asked the students to take a look at all the pictures. Most pictures looked great, but when a picture of a rose with butterflies flying around appeared, the classroom were surprised. 

"I don't get it," Tom said, "I thought we should draw a rose, not butterflies. " "What's wrong with the butterflies?" Mary asked. "The butterflies are a fantastic idea," said Mr. King.

"Fantastic?" the class asked, shocked. "Yeah! It smells sweet. " Mr. King continued. "And who do you think knows more about sweet-smelling flowers than butterflies?"
