When you're learning a foreign language, the key question is not how fast you can make sentences and be understood in that language, but how can you understand the reply coming from the other person !!!

For starters, it boils down to this: you speak in Arabic ( Ya walad... Ya oustaaz, Ya Bey... Ya Mouhandis, etc) and ask the other person to reply in English... LOL

It is the same if you're trying to learn Spanish and travel to Cuba for example (where people speak the worst Spanish on earth), yes, you will be speaking to them, but no, you will not understand them.

But do not get discouraged, it is a very long process, and you have to be exposed to the language full time at home, at work, on TV and by reading newspapers and most of all, as one of my Spanish teachers used to say; try to understand the lyrics... in songs...!!

Yalla... good luck !
