I therefore approached him [Chopin] with considerable trepidation, and great was my disappointment when he told me that he no longer took pupils. He, however, kindly invited me to play something, to which he listened carefully, and then made some unpleasant remarks and advised me to take lessons from one of his pupils. As I was about to leave him he offered to play for me, saying that it might prove useful to me to hear him. I accepted eagerly and was full of expectation, when he sat down and played a new piece of his composition, entitled 'Le Fou,' one of the most reasonable and dullest pieces ever perpetrated. I admired the elegance and neatness of his scales and legato playing, but was not otherwise struck by his performance, having expected more, and wondering at some wrong notes which I had detected.
