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.
School started teaching us when I was 11 but I had learned a few things before that, mainly from video games
Do you know which games? I learned English at age 3
