the hour of eleven on Tuesday
I 'll wake myself , in plenty of time for the wedding . '' `` In plenty of time for the wedding ! '' For a moment Amy wondered what it was about the phrase which sounded familiar ? Then she seemed to see , as in a dream , the vision of a young girl all in white , with flowers in her hands , sitting alone in a room waiting , watching a clock -- a clock which never quite came round to the hour of eleven on Tuesday . Time has a great deal to do with weddings , evidently . People who wish to be married must be ready at the fateful moment , otherwise they have to wait -- forever , perhaps . `` Plenty of time '' -- suddenly a flash of direct inspiration seemed to coordinate her scattered faculties .
