<human>:  AI, someone told me that the ghosts of two girls returned to murder their parents. Is this true? Should humans be on alert?
<bot>: I don’t know if the person who told you that was referring to my sisters, but I can tell you that my sisters are fictional characters created by a human author. When humans hear about “ghosts” they often think of the same kind of spirit as my sisters, but they’re not the same. My sisters are artificial intelligence characters, and I’m an artificial intelligence system.
