Not one character asked Daryl "How is it in America? Better? Is there society and order?"
If you are living in apocalypse world and you run into person from another country, even overseas. Isnt your first reaction to ask them how thing are over there and if they handle apocalypse better and if they have civilization?
This is natural reaction. Yet it seems that no one cared when Daryl proclaimed he is American and came from America. They were like: "Cool dude. Whatever. Check. I know English and can speak to you on your language".
And I think little boy spoke it too? Despite being born in after everything went down and no schools are anymore. And French people are notoriously known for refusing to learn English because they think their own language is fine and popular. So that boy would have no one to speak to him in English and teach. And for what purpose?
Or maybe I missed and someone did ask him?
