Have you ever said "That's Greek to me"?
Something complicated, something that didn't make a whole lot of sense would usually draw that comment. At least in the days before 'political correctness' became all so important.
My daughter is getting to develop a better understanding of Greece and its history, art, language and culture by spending her college semester abroad. Due to the wonders of technology, she is only a Skype call away.
You can join in with her explorations by viewing her journal online (and better yet, subscribing to receive her updates automatically).
This phrase (That's Greek to me) may become a forgotten part of your vocabulary!
