An American friend is self publishing a book. It's set in Scotland, I'm Scottish, and she asked me to look it over to check if the accents are relatively accurate. They aren't, at all. I pointed this out and gave her some tips, which she completely disregarded and laughed off as she said only Americans will read it and they won't know any different. So why bother asking me?
She's now asked me for help with proofreading but I don't feel inclined to do so as she obviously isn't that interested in my advice.
AIBU to refuse to help her?
