"...and knew it was going to be a difficult day." (pg. 38)
The idea of a day and the importance a single day can play in a simple life. Laura Brown predicts that it will be a "difficult day" and she is right. Over the course of one day, Laura debates suicide and essentially decides to leave her family because she knows that if she stays with them, she won't survive. This day in her life is pivotal, much like the three other days that relate to hers (Virginia Woolf's one day, Clarissa Vaughn's day and Clarissa Dalloway's day), important things happen within one day because really, one day is simply a life lived within twenty four hours.
