Transplanted Canadian living in Houston, TX. They broke me of saying 'Eh' early in my stay here but as soon as somebody hears I'm Canadian they can't seem to resist the, 'How's it going....EH?' GFY.
I have learned when and where to say y'all, but it makes me smirk every time. It will never be natural.
My wife, a Texas girl, makes fun of the way I say the word 'sorry'. Down here it is closer to 'sahry'. I remain unapologetic.
