The weather is very hot where the story takes place. I feel that Carol is miserable because in the desert it's hot and she wasn't prepared to be in this type of weather. I also feel that she isn't happy about going to her grandpa's ranch because she wanted to hang out with her friends and have pool parties instead of going to her grandpa's ranch.
Carol's grandpa's ranch is in the middle of nowhere and the only person there is grandpa Serge. I feel that because there isn't anyone living at the ranch except for grandpa Serge I feel that he is lonely and sad.
