sigh. OP, well the good news is you can find some of the cultural practices right here at home…citizenship, voting, etc. And improved!
I read somewhere that the Greek word for "traitor" is synonymous with the guy who showed the Persians the back way past the gates of Thermopylae. I have no idea if this is true but I bet a Greek-speaking DCUM person could verify or discredit this.
Hey, btw, there is a great read, one of my favorite books, about Thermopolylae called "Gates of Fire" by Stephen Pressfield (or Steven). It's a novel and I think Mel Gibson bought the rights for the movie but sat on it and then "300" came out so he's still sitting on it. Darn Mel Gibson for doing THAT (as well as his other, more well-known, affronts).
