Hi galisteo,
I agree that Caroline was under a great deal of pressure to be the perfect princess. I think that sometimes maybe Grace was a little tough on her but Caroline was not exactly an easy going child. I think Grace saw in Caroline some of her own wild behavior from when she was young and this made her nervous.
From what I read in Jeffrey Robinson's book
Rainier and Grace Caroline begged her father to let her marry Junot. Of course this is only one side but it is a little puzzling.
I think Caroline was probably guilted into duties as a child but she seems to enjoy her royal lifestyle quite a bit. I think Caroline enjoys what her status and money brings her now and I would imagine that some of the quotes that I highlighted were made in earlier days. I also agree that it would be fascinating to have more interviews on Caroline avaliable. All of the Grimaldi children are engimas to a degree. Understanding them better would be a fascinating course of study.
