Ol' Murphy seems to pervade every aspect of life, even those aspects we otherwise designate as times and places for relaxation.
Example: the bookstore.
The Twit, if you must know, like many a misguided youth who's been lured by the siren call of reading, has a book stash that borders on small-library-branch-worthy. Sometimes she makes an attempt to rein it in, wrangling stray books and neglected titles into a bag or box to be sold to the used bookstore.
This brings us to Murphy's Rule of Bookstores #1:
The day one has finally mustered enough self-control to rid oneself of a significant number of books is the day that the used bookstore stocks the shelves with books that will sorely tempt that self-control and threaten to undo the progress made.
And Murphy's Rule #2:
The day after one has acquired a long-sought book is the day the used bookstore has said coveted book in stock.
Am I missing any rules here, bookish folks?
