“You sound like Hagrid,” said Ron. “It’s a dragon, Hermione, it can look after itself. It’s us we need to worry about.”
“What do you mean?”
“Well, I don’t know how to break this to you,” said Ron, “but I think they might have noticed we broke into Gringotts.”
All three of them started to laugh, and once started, it was difficult to stop. Harry’s ribs ached, he felt lightheaded with hunger, but he lay back on the grass beneath the reddening sky and laughed until his throat was raw.
