Yes you're right, they're Khaleeji and what they meant was "let's sit down". You seem to know a lot about Arabic since you know about the numbers and the letters. Meera, you're right too, I'm from the Maghreb region (Morocco) and we do use g in most cities but our accent is totally different, you might wanna consider it a language. By the way I just noticed that you speak Arabic, I'm glad to have you here, both of you
