midnight
`` Good heavens ! What a learned man ! '' thought Mimi as she brought the coffee and pipes . However time was getting on , midnight had long since struck , and Rodolphe sought to make his guests understand that it was time for them to withdraw . Marcel , who retained all his senses , got up to go . But Schaunard perceived that there was still some brandy in a bottle , and declared that it could not be midnight so long as there was any left . As to Colline , he was sitting astride his chair and murmuring in a low voice : `` Monday , Tuesday , Wednesday , Thursday . ''
