`` Of course it is , '' said Patty , `` and you do n't look a bit old either . Why , you look as young as Mr. Hepworth , and he looks nearly as young as Kenneth , and Kenneth 's only two years older than I am . '' `` That sounds a little complicated , Patty , but I 'm sure you mean it as a compliment , so I 'll take it as such . '' A little before eight o'clock , Patty , in her shimmering gown , went dancing downstairs . The rooms were already crowded with guests , and the first familiar face Patty saw was that of Mr. Hepworth , who came toward her with a glad smile of greeting . `` How grown-up we are looking to-night , '' he said . `` I shall have to paint your portrait all over again , and you must wear that gown , and we will call it , ` A Moonlight Sonata , ' and send it to the exhibition .
