In this movie, the main character, Carol, is a young girl whose mother is from Spain and her father is American. She moves to Spain with her mother. Many times in the movie, Carol fights against the conventionalisms in the new culture. An example of this is when she continues to wear the types of clothes that she chooses, and doesn't change her style to that of the other kids around her. She wears her "tom-boyish" attire, like her bib-overalls and keeps her hair cut short.
She insists on wearing a sailor outfit for her first communion instead of the outfits that the rest of the girls do.
Carol is very mature for her age and knows what she wants and how to get it. She tends to use the "You promise?" and "On one condition…" approach to get her way, especially with her grandfather. Carol was free-spirited and used to doing her own thing. She wasn't going to let anyone change her or force her to do something she didn't want to do. When she put her mind to something, she did it, like writing letters to her father so he wouldn't worry, or bringing Tomi home to meet her father, even though her grandfather told her it may be dangerous to do so. I wonder if Carol felt any guilt when Tomi was killed.
