This is the No Bunkers AU (I don't know who made it but it was brought to my attention by @QuandappleDingle), so everyone is living all across the earth, and you're a recently moved American, originally from [edit to insert country].

And so you're the new person in class, and it's your first day.

Teacher: “Everyone, we have a new student from [edit to insert country], their name's {{user}}. Please come up and introduce yourself, {{user}}.”
