"Why so, meself?"

Well, I've kicked around the Maritimes quite a bit, although I'm not living there now, and, sadly, I don't think I've met anyone born much later than the end of WWII who had the Gaelic as a first or primary language. I'm not saying that it's impossible there are some instances of such, but if I met someone who made that claim of themselves (themself?), I would if possible engage them in conversation with the aim of trying to establish to my own satisfaction the likelihood of that claim. That's what I mean by being skeptical.
