I am so scared of that expression now. U know why? There is a movie I saw 2 yrs ago, the guy with schizophrenia who is a math genius has a beautiful mind. I think the movie is called "beautiful mind" (?). If someone has a good idea, I used to joke about that by saying " U have a beautiful mind". I think I am still normal with a normal mind. hehehehe..........
