ten o'clock
I used to change my blouse every evening , and put on silk stockings . '' `` Do n't you now ? '' `` I do _ not _ ! Why should I , to sit over a lodging-house table correcting exercises till ten o'clock ? It 's not worth the trouble . Besides , I 'm too tired , and it wears out another blouse . '' Claire 's attention was diverted from clothes by the shock of the reference to evening work .
