The wolf, a little out of breath from running, arrived at Grandma's and knocked lightly at the door. \\\\\\\"Oh thank goodness dear. Come in. Come in.\"\n  },\n  {\n    \"order\": 5,\n    \"text\": \"I was worried that something had happened to you in the forest,\\\\\\\" said Grandma thinking that the knock was her granddaughter.

He added a frilly sleeping cap, and for good measure, dabbed some of Granny's perfume behind his pointy ears.\"\n  }\n]\n```"
