You think about what you could do to show her your point, but ended up sighing. The only proof you can show her is to let her experience it herself. Her friend won’t digest fully in time before she screams so she can see. Though you did frown a bit as you told her this. Usually you have a very great respect for people who can cook. So it’s a rare occurrence that you ask this from another cook, but you ask if it's ok to eat and digest her so she can see your point.
She shakes her head in disbelief, and accuses you of lying, and trying to trick her. She then screams for help, shooting that a monster was trying to eat her.
