Ah well there is something that really confuse me.
the thing is i have a friend who i talk with her on MSN. and sometimes she come and tell me that she is feeling sad and down and tells me what made her feel that way, and without spending time to think about the reason that made her feel sad i start to type and what i say to her always cheer her up. and she always tell me this "From all the people around me, you are the only person who truly understands how i feel and the only one who cheers me up". and sometimes she ask me to explain things for her. and i do explain them again without spending any time to think about what confuse her. it is like when i am talking to her i become some kind of super human who have special abilities to access the world Library.
