Continuing the lunch time scene involving Carl, James and Mavis, who has just returned from clerking a patient. Her exasperation with her patient reflects the frequency at which I encounter such a similar emotion. The lesson out of all these is gaining the understanding that humans are fundamentally prone to making less wise and rational choices in their lives, like refraining from eating fatty oily foods. And that include ourselves, whom we have a tendency to view as infallible.
