Teaching English

Hi to you all

A friend of mine says his brother and his family moved to Mozambique a couple of years ago, and that they all say they never want to return to South Africa ever again, thank you very much! I recently put up an advert on the the website for teaching English there in your paradise. What I want to know is: will I be able to cope, speaking only Afrikaans and English, if and when I eventually get there?
Greetings,
Frans
