Holly seemed much older in the book (I don't know the movie)
Do you agree with me that Holly in spite of her being that childish, too emotional etc., seemed much older than your average girl the same age living now? I mean - she lived on her own, she took care of herself, she participated in adult activities like she wanted to get married, went on trips with friends, went abroad, had money to spend, for example on buying pieces of furniture - all of those rarely happen in case of teens now. I mean, she lived on her own and didn't need any parental consent for doing this but, to use a Polish idiom, I'll sooner grow a cactus on my hand than believe than an average 18 year old (or a younger girl and she didn't run away from home at 18, don't forget) would be as good as doing that many things on her very own. She generally hung out with much older people so maybe that's why she seemed like a woman of 30 rather than a teen (even an adult one), I mean - she led a life of an adult, she was more interested in adult than teen stuff.
