if you change your mind, let me know.Oh man, I tell you what, if we were casting about looking for a destination for a European vacation this summer, we would absolutely take you up on that!
Chios is not a touristic island. Plus it is pretty far from Athens. As opposed to the Kyklades where you can take a ferry that lasts just a few hours, the boat to Chios is an overnighter (or an hour flight). Also, many of the Greek shipping magnate families are from Chios. I don't know the history of why so much of the merchant marine came from that island.I've never heard of this island before reading that post - likely a testament to low-quality geography education in junior and senior high school!
It is hard to type the proper pronunciation. I guess the closest would be "HEE-os" where the H is much stronger than the English language. But since you mentioned Spanish, it would be more like the Spanish j.My Spanish-English speaking brain instinctively wants to pronounce it something like "Cheetos" but without the "t" - is that even close to correct?
Don't worry, the way gyros is mispronounced is of great national concern for Greece!

Anyway, I hope you will try the exercises with your wife and give me feedback on how they can be improved, as nothing I teach is set in stone. I'm always looking to do better.
