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.
Tear Jerker: When Elizabeth comes home after 'rescuing' Celia, only to find out that her dog died. It's horribly driven home when she gets a letter from the Society for Best Friends saying "Lochie was probably lying there, crying for you, wondering why you never came back." *SNIFF*
And Celia never shows her any real compassion!
Not to mention, Elizabeth also finds out that Christina wrote her a bunch of letters asking for advice after possibly getting pregnant, and spends a while feeling horrifically guilty that she went to help one friend while others needed her, especially when Celia starts getting distant.
Christina breaking down and blaming herself for Renee ending up in hospital.
