My wife's native language is Spanish and she hates when I use ungrammatical constructs because she trusts me to model correct grammar for her. I, on the other hand, have superlative grammar but enjoy applying other language's grammatical constructs to English. I just workshopped a story with my writing group which is written in a synthetic pidgin that I created for the Burkinabe characters in the piece. There was some admiration for the technical achievement, but concerns that it might be offensive having come from a white author, a concern that I had as well.
