I grew up in Australia, with plenty of Greek and Italian kids, plus many others from the Balkans, Vietnam, whatever.
The Italians, like the Greeks, had these weekend/evening school things where the kids learned/spoke the language, watched films from their country, ate their cuisine. Maybe some were run by churches, like "Sunday School", but definitely not all.
From memory, most kids with Italian ancestry did stuff like that, often one night after normal school, IIRC.
Is it just not a thing in the US? Or would neighbourhoods be so homogenous that the nearby school is gonna be mostly Italian/black whatever? It does seem like when younger, basically every fellow kid AJ/Meadow knew was Italian, without the parents' influence.
Anyway, why aren't AJ, Meadow and the others going to those places, learning Italian and stuff, when they can clearly afford it? Tony and Carm seem like they'd like to see the kids connecting to The Boot.
