one o'clock
Fontan , as became a philosophic spirit , declared that all men of fashion were beasts whom it was one 's duty to despise . And from that moment forth Nana was full of very real disdain . That same evening they went to the Bouffes-Parisiens Theatre to see a little woman of Fontan 's acquaintance make her debut in a part of some ten lines . It was close on one o'clock when they once more trudged up the heights of Montmartre . They had purchased a cake , a `` mocha , '' in the Rue de la Chaussee-d'Antin , and they ate it in bed , seeing that the night was not warm and it was not worth while lighting a fire . Sitting up side by side , with the bedclothes pulled up in front and the pillows piled up behind , they supped and talked about the little woman . Nana thought her plain and lacking in style .
