A thing to remember!
I always get a surprised reaction from other Americans when they find out I'm from the Middle East and am a Christian. Their first question is "When did you convert?", on the assumption that all Middle Easterners are Muslim. Without getting into theological niceties, I reply that my family was Christian. When they counter with, "When did your family convert?" I reply off-handedly, "Somewhere around 70 A.D." That usually elicits a puzzled look or two.
