Thus far in A Thousand Acres we have learned many different things about all of the characters but i think Caroline is one of the most interestingly different characters when compared to King Lear. What still stands out to me about this character though is when she got in an argument with Ginny at church. It was an earlier passage but it was the first time we got to see who Caroline really is. In this passage we see that Caroline is tired of having to act like a little girl to her father and this time she will not sit there and try to appease him just because it's what he wants.
Caroline is tired of doing what everyone wants her to do, so in this chapter she stands up to Ginny and tells her that "It's time to stop making allowances." By this she means that she doesn't want to receive the farm from her dad and that it should be her decision what she wants, and no one else can make it for her. Caroline is a strong person who wants to make decisions based off what her interests are, and not what her father tells her to do.
I think this passage really sets the tone for how Caroline is going to be throughout the rest of the book and she even shows this is true by, when her father slams the door in her face on the porch she doesn't wait around for someone to come find her. Instead when everyone does come out of the house she is gone.
