I posted this question as an aside on another thread, but everyone is ignoring it as not being the point of that thread 
So, DD1 and I were reading a book last night that I read as a child. I knew this sad chapter was coming up, in which one of the parental characters dies, and the chapter talks of what a good man he was and how much everyone loves him. I could feel DD wriggling next to me as I read and I stopped and asked her if she was ok. The poor little soul cried out 'I don't like this chapter' and burst into tears. I remember crying at this chapter every time I read the book as a child.
Can anyone tell me a good reason for sad bits in books? She asked me this, and I couldn't think of a good reason. Her exact question was 'Why do they [the authors of books] make the young people die? It's not like [an elderly character] dying, I'm expecting that! Why is it a good idea to make sad bits in books?'
Help!
