There is a blog called The Writing Endeavor (http://thewritingendeavor.blogspot.com/) that seemed like a good idea, if only a little nascent and non-secular. The request for the first week was to "have your character give a reason why he or she likes (or maybe even dislikes) the end of the week. It could be something trivial or something huge (there's free lattes at the coffee shop on Saturday nights, or your character gets a break from work school, etc)."
While I have not written anything on the story I have in mind, I do know what the character is like to some extent. With that, I was able to formulate a response, though it is quite short:
The end of the week means the weekend is nigh, and schedules change. Expectations are different then, and excuses become far thinner. Maybe I should just change my work schedule. People don't notice when you're not there on a Tuesday when they're busy with their own lives. Yes, that's what I shall do.
