I suppose I can speak both American and Queen’s English, though I grew up with the latter (my dad is from England).
I learned starting at 3 years old 😊
Now, I am onto a third language of Galician, which is spoken in my country. Maybe I will even learn a fourth for my Japanese girlfriend but her close/immediate family all speaks English.
Wow!! Amazing!!! My friend has Norwegian as her second because it’s what she was learning second but also Norwegian as her, like, third or fourth. She is not at all fluent in Norwegian but it’s her childhood language.
