"Me too," replied Lisa who was sitting on an old trunk. They were in a newly built building with fancy furniture in it. "I wonder where that came from?" said Jonny. "I think it was one of the pieces of machinery," answered Lisa.

"What machinery?" snapped Jonny.

"You know, the one in the basement," shouted Lisa because the noise had started again. Just then Lucy walked in and said "I overheard you arguing about the whistling noise. I heard it too." "Oh yeah, now I remember, the machinery that makes ice-cream," Jonny said.
