eight o'clock precisely
Vorotov asked her questions , and at the same time kept looking at her fair hair and thinking : `` Her hair is n't naturally curly ; she curls it . It 's a strange thing ! She works from morning to night , and yet she has time to curl her hair . '' At eight o'clock precisely she got up , and saying coldly and dryly , `` Au revoir , monsieur , '' walked out of the study , leaving behind her the same tender , delicate , disturbing fragrance . For a long time again her pupil did nothing ; he sat at the table meditating . During the days that followed he became convinced that his teacher was a charming , conscientious , and precise young lady , but that she was very badly educated , and incapable of teaching grown-up people , and he made up his mind not to waste his time , to get rid of her , and to engage another teacher . When she came the seventh time he took out of his pocket an envelope with seven roubles in it , and holding it in his hand , became very confused and began : `` Excuse me , Alice Osipovna , but I ought to tell you ... I 'm under painful necessity ... '' Seeing the envelope , the French girl guessed what was meant , and for the first time during their lessons her face quivered and her cold , business-like expression vanished .
