Is This a Trick or a Real Girl!?

For almost a month I received e-mails and offline messages from a girl with a dr_hellen ID in YAHOO Messenger. Once there was an opportunity to talk to her on the net, through the Mic. She (Named Sara) told me that she was 29, currently a dentistry student in Tehran Azad University and has two more semester to finish it. And more. We talked for at least 1.5 hour. But that's not something extraordinary. I've talked to many on the net and phone. The point is her voice was so clear and instant that I think she lives somewhere in Canada or the States and it might be one of A. J.'s tricks! I mentioned that and never heard from her since.
