>Very simple - the people think that Sergey is their friend, but it is simply not true. This is an illusion. I thought the same way myself - it is hard to explain - when somebody is helping you as much as Sergey does you start to feel as he is your friend. He doesn't at all feel the same way for anyone here, I believe.
