^personal taste.
Her English isn't great and that's not typical Dutch haha but who cares. She looks really cute and sweet and also young, very fresh with lots of energy.
At wangster: She was 15 at the time, now she is 16. I believe there are some rules about the age in Paris. Also It could very well be that school said that to her. It's her last year which means exams and you can't miss to much.
There is one week holliday in the neths, i believe 19 till 27th february. She is also 16 but it could very well be that she skips a week (or maybe she has a excl.) because of school.
