For almost three years, I've maintained my resistance. I insisted it sounded wrong in my accent. When you've been an expat for long enough, the small irrational cultural quirks that you've retained suddenly assume a disproportionate importance. You cling to them, blindly and desperately, as if your stubbornness were a life ring and you were drowning.
This past week, I finally cracked.
I started saying "Cheers" instead of "Thank you".
