As an American living in the Middle East, I get the question on a regular basis: Are you a spy?

Others aren't so direct but I hear their whispered suspicions on a regular basis. Whether or not I'm a spy of course will just have to remain a mystery. I wouldn't want to blow my cover by admitting something like that online after all.

However, if you're trying to figure out if your new friend is a spy or not, check for these signs.

1. He or she has an expert knowledge of a regional language or languages

Arabic is usually the preference. If they are fluent in Arabic, Farsi and Turkish, be very suspicious.

2. No job (or a low-paying one) but always seems to have money

Maybe just rich parents? Or maybe Uncle Sam is footing the bill ...

3. And usually an exceptionally nice apartment

No job? No money? Best apartment in the city? Rich parents, I swear.

4. Always seems to know far more about regional politics than you or any of your friends

He or she should really just pretend not to know this stuff.

5. And is very interested in any political leanings or connections people have

If his or her ears perk up every time you mention Hezbollah ...

6. There's a really good cover story

It might be education, working with some NGO or volunteering. Remain suspicious.

7. But also very few details

You never quite understand exactly what they are studying or doing in their volunteer work

8. Politely changes the subject every time the subject of spies comes ups

Regularly dodges the question when asked directly

9. Has a number of friends that are equally suspicious

So, all of their roommates lived in Iraq, Afghanistan and Syria before moving to Lebanon? Interesting. Very interesting.

10. May often have very pro-Western political leanings

But, the best ones pretend to be leftists. Don't be fooled.

11. Travels regularly and without warning

Oh, you went to Iraq this weekend for fun? How was that?

12. May decide to leave the country indefinitely after previously committing to stay longterm

You just renewed your residency and now you're leaving forever?

13. Always uses vague reasons to explain these decisions

Just smile and nod.

14. After deciding to leave and disappearing for several months – or years – he or she suddenly shows up again without warning

You just can't get rid of them.
