These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Was Pauline right for blaming her distant relationship with Jane on her job, or had they never really got on and she was using her sister's commitment to her work as an excuse for avoiding her?
In the last series, Jane calls her sister a cow. In the first, the present that she got for her newborn baby was a cow plushie.
Values Dissonance: This Troper gets the impression that we're supposed to be scandalised by Jane's apparent callousness when she interrupts her doctor to ask about going back to work after her abortion but, depending on your politics/beliefs etc., this might seem like a perfectly reasonable reaction, especially if the experience hadn't been as bad as she might have originally thought it would be.
