Ever wonder how to "interact with the local populace" when you travel somewhere? Well, here's how it's done:

    - Be prepared to discuss your personal interests (hobbies, books, travel).
    - Be sensitive to your body language.
        -> Smile as long as it is appropriate.
        -> Avoid sitting with your arms crossed.
        -> Do not show the bottom of your feet in an Arabic  culture.
        -> Keep your hands away from your mouth.
        -> Lean forward and nod.
        -> Make frequent eye contact (if culturally  appropriate).
    - Use the person's name, position title, rank, and/or other verbal expressions of respect.
    ...
