I have purchased a book on language in Bali. The book says there is two versions of the language. One being common Balinese (lumrah) and the other being refined Balinese (alus). If I do not know the person that I am talking to, do I use lumrah or alus as I do not want to cause any embarrassment to anyone. I have searched the archives and could not find the answer.
Thanks
