But it's just a story, and it's our story at that. I am telling you this story, and you ask me how could I know.

To make my story more palatable, I can add another line. I was the nurse who delivered the boys. As the result, I developed an attachment to the boys, as well as to the mother, who was a single mom too. So we stayed friends after they left the hospital.

The time went by. I continued in my job which paid for my graduate studies and eventually landed a job in a mental clinic. When the liar boy - now a grown up fellow - felt sick, his mother - now my dear friend - sought my advice. So I was in a position to observe the said change in boy's behavior.

In fact, the change was not that sudden. The boy, while in the hospital, began experiencing doubts about his beliefs and shared the doubts with me, his doctor.

Right, in my story he does no such thing. He only answers questions when asked.

> because he wants to lie and he doesn't
> want other people to know that he is

No, as far as I understand - or rather remember - our conversations, they boy did not care about what other people think, not a little bit. From the birth on and especially after his illness, he was absolutely preoccupied with his own thoughts. He still is.
