Option 1

I chose option 1
If I were Caroline, I would be nicer to her. In the novel Caroline was said to have no interest in Louise and bossy and think highly of herself. So if I was her I would figure her problem and try to get on with it. To be friendlier with her I would talk more to her, and give her my interest in what she is doing  even though she might think what's my problem I would try and try again to be friendlier.
