The british say "are you alright?" and in australian culture that means they are "worried" about you and about to cause you a problem. Or they think you are causing a problem.

I dunno which culture you are from but "kako si" or "kak si" were normal things to say in yugoslavia and bulgaria. "hoe gaat het" in the netherlands.

I always thought people were never that serious when they said it, in any of those places or back home in australia. I am curious to know where people take such questions more seriously because that sounds like a good culture.
