I keep reading Sociolinguistics and language education. Today I've learned that, regarding the intercultural interaction, my view is much closer to discursive-constructionust perspective than sociostructural/rationalist.
Among many aspect, I see cultural diversity as an interactional resource, and I don't see it being hazardous, source of miscommunication.
The chapter on language and culture is as great as others in the book.
