“I don’t get it,” said Ralph. “Why is the expensive time in the afternoon?”
“I bet I know!”, said Samantha. “It’s because everyone is working really hard then!”
“Yes,” said Bobby, “and also because that’s when it is the hottest part of the day, and all the Zerv Air Conditioners are working really hard, and because they are Papa Zervs, they eat lots of Berries.”

“Well,” said Linda, “I sure like the Zerv Air Conditioners. They make the house way more comfortable than just a fan.”
“Yes, that’s true,” said Ralph. “But it looks like we need to pay more attention to what and when we ask the Zervs to do for us if we don’t want our Berry Bill to go through the roof.”
“And,” said Linda, “we don’t want the sky to be clogged. Today at the Hospital I heard that the weather patterns are changing—it is getting hotter and there is less rain.”
