So, dear Muhammad , I can even understnd why Your relatives lost their language!
It is not easy to teach languages like Adyghean.
Generally remember, while gergian is an easy language, Adyhe/Abkhazian, and some Daghestani languages are among the most difficult languages of the world for their gramar and for som of the sounds - so it requests a lot of work to learn them - that is why native speakers often easyly loose their language once away form homelands.

Excuse me but with that I finish my posting today - I will relax a bit - perhaps I come back a bit later my friend!
