We need many more like this. No way i can remember a preposition is followed by accusative with one example that happens amongst all of the other lessons.
προπαντων για τους γονείς Was disallowed. I think this is an acceptable alternative in the context of this sentence.
Wow! I really don't understand the word order, here
In English you put possessive+noun. In Greek, it is definite article+noun+possessive.
Ειδικά = Especially,
για = for (prepositions are followed by accusative)
τους γονείς της (in accusative because of the preposition) = her parents.
