Which two elements does this excerpt from a christmas carol by charles dickens contain?

“There’s the Parrot!” cried Scrooge. “Green body and yellow tail, with a thing like a lettuce growing out of the top of his head; there he is! Poor Robin Crusoe, he called him, when he came home again after sailing round the island. ‘Poor Robin Crusoe, where have you been, Robin Crusoe?’ The man thought he was dreaming, but he wasn’t. It was the Parrot, you know. There goes Friday, running for his life to the little creek! Halloa! Hoop! Halloo!”

Then, with a rapidity of transition very foreign to his usual character, he said, in pity for his former self, “Poor boy!” and cried again.

“I wish,” Scrooge muttered, putting his hand in his pocket, and looking about him, after drying his eyes with his cuff: “but it’s too late now.”

“What is the matter?” asked the Spirit.

“Nothing,” said Scrooge. “Nothing. There was a boy singing a Christmas Carol at my door last night. I should like to have given him something: that’s all.”
