Brilliant. I think of this more often than I probably should. Through traveling, I have noticed that it is a very western thing to say “I’m good” as soon as someone asks “how are you?” When I lived in Cambodia for a year, all the local Cambodians I met would simply respond with “fine.” If you think about that, that would be a more appropriate response then good because fine doesn’t represent neither good or bad.
Cultural norms are always interesting when it comes to human behaviors.
