Tips when joinning the country

Hi,
I'm not often on this forum these days but perhaps I can answer your questions:
1) Kids, they love them everywhere in Tunisia. EVERYWHERE.
2) Sorry, can't help.
3) Where to live? With no personal details about you, I would say live in a larger town or a city if your speak no Arabic. Since tourism collapsed, most Tunisians speak Arabic and though most can speak some French and some can speak English, Arabic is by far the dominant lingua franca. Used to be French was spoken everywhere, but that's changed.
4) Safe? I don't think I've ever lived in a country where I felt safer than here. My only concern is that some Western nation will start bombing Libya again and that might create problems. The Tunisians are friendly, welcoming and genuinely nice people.
Good luck!
