A Jewish friend of mine always seemed a bit ambivalent about the Jewish religion, there were odd things, like her belief in the shroud of Turin. (When people ask me how I was raised I have to say "as a science experiment.") But after my friend moved away we wondered what sort of card to send. We tried to find the right pc phrase, gave up, and settled on "Happy Holidays, Christ-killer!" which worked fine. Denoument: Later she told us she'd become an Episcopalian. And I once met the man who did the first scientific appraisal of the shroud of Turin. He has a lab south of Chicago.
