Hellooooo

I received another call from Iftequar. He lives in Riyadh (Saudi Arabia). He's called me at least half a dozen times... Most of the time for short conversations, asking how I am and where I am (?)
I've received phone calls from Nigeria, India, the USA, Tanzania, Pakistan, Hong Kong; those are the ones I had the chance to answer to.

The question is, why do I give my cell phone number to potentially dangerous or at least idiotic people I meet in chat rooms? Well, they live in far and distant countries, and of course I don't pay one cent when I receive international calls -stingy me-... It costs about US $0.30 a minute to call to the US and I'm pretty sure it's the cheapest place to call, from here, on my cell phone. It's supposed to cost about 25 cents if I buy the new calling cards they are selling these days. Just imagine how much it would cost to call people in far and distant places like India or Nigeria or Saudi Arabia or Pakistan or Egypt....

Now, can you guess why those people are calling me?
