Some Goodreads reviewers say:
- "While walking along they see a man hit by a car. Nobody helps him, pretty soon a van pulls up and men get out and load up the bleeding man. Everyone acts like nothing has happened. When Kaida mentions it at home to her brother she is told not to talk about it."
- "But it will leave you with the lingering question: how is moldy cheese unnatural?? ;)"
