You are quite welcome, dear heart. And you are correct: it will be a neat distraction for you. (As well as a source of pleasure for me: whilst there are several places I might go for a conversation in Russian, there are fewer speakers of Arabic with whom I might converse.)

Do send me your exercises as you complete them -- there are several errors that are very tempting for beginners, and once they've set into one's memory it is a bear to dislodge them. I also believe I've found you a tempting primer for once you've mastered the basics, but I shall continue to be mysterious there.
