Cultural sensitivity

My cousin & his wife had a series of evenings in which they explored the cultural traditions of different peoples. They are Christians, but enjoyed preparing shabbat supper; not a kosher meal, just learning different songs, prayers, blessings, etc that might have been part of their Friday night ritual had they been Jewish.
Happily, there were no actual Jews present, since my cousin's wife prepared what she often finds convenient to fix for large groups: pork roast.
