Many moons ago I worked with an Egyptian Database Administrator at the Saks data center in Jackson, MS. Besides Arabic, he, obviously spoke English, but his English was better than 99%of the native speakers in America. He also spoke German as his parents, two college professors, had taught in Germany for many years. He was and is a very bright man in many ways. He originally trained as an engineer, but discovered better money in administering huge corporate databases.
I was reasonably friendly with him, to the point of eating dinner at his house. He was secular, but his wife was a very devote Muslim. I remember asking him if Muslims believed in hell. He responded adamantly with, “Oh do we ever believe in hell.” And a tough hell it is, but you can get out of it, unlike Christian hell.
One night, at her request, I attempted to elucidate to his wife the various Christian denominations. I gave up in a short while as it was very tough slogging. I did gift her a book on the various branches of Protestantism from either the Dummy series or Idiot series of books. I really does boil down sometimes to how many angels are dancing on the head of a pin.
I wish I had had this little video to point her to.
