I worked closely with a Jewish man for many years and always quizzed him on the meanings and traditions of his various holidays (they have a LOT of them) at our Friday office lunches. He was never real forthcoming, just kind of brushed them off as 'minor' holidays. Sometimes he'd tell the back story, but not often. Often while munching on a combo pizza, definitely NOT kosher...
Meanwhile, Happy Hannukkah to those who celebrate!
