I really don’t understand where this question comes from. I guess it’s a clumsy translation of the local formalities. My answer is always “Christopher” (which inevitably comes back as “Mr. Christopher”), since “Chris” can easily become “Krishna” and “Conway” is just a waste of everybody’s time. People here know the name “Christopher” the same way Americans know… Um… Are there any Indian names that Americans know? “Vijay”? “Ravi”? (Stupid Americans.)
