> maybe bilingual couples have a communicative advantage? That would be the happy path but This seems to cut both ways depending on mood: benefit of the doubt has to be stretched when you don’t master the language (and cultural references etc) but you can also be maliciously misinterpreted in wrong ways (opposite of benefit of the doubt). Then, switching languages mid argument takes on significance and so on.
