Coincidence, noun: a striking occurrence of two or more events at one time by mere chance.  

They met, as many do, on a sunny day in April, forty seven days after Valentine’s Day (if that sort of thing is considered important).  

She had walked along the beach, as she did on most Thursday afternoons, and was dutifully reading a book that had secretly been put off since January.  The cup beside her sat untouched, the spring breeze cooling it as it passed (she did not really want it, but could not sit outside the cafe without some sort of monetary offering).

 He had mud on his shoes that day (the shoes were new and it seemed to be important at the time, whereas the story of the mud is not) and was somewhat self conscious because of it, which may sound strange.  If you knew him it would be perfectly normal.

It could be said that at the time they were two very different people.  It could be called a coincidence that they even crossed paths that day, so different were their lives.  She was a student, or had been (she had decided the year before to take a year off, and now she seemed to drift along where she wished).  He was an anthropology major, with a strict view of humanity that bordered on the mechanical.  

He was walking down the sidewalk of the small cluster of shops in the hope of finding something, though he can never remember what (it doesn’t seem to be important, in retrospect).  She was waiting for her friend, who would be late that day but would happen to fall into step a few feet back from a dark haired boy with mud on his shoes.  

Though he cannot recall the time of day it was or the name of the cafe, he emphatically remembers the girl that sat outside the coffee shop, leaning into a book passively.  At the same time that he happened to glance her way, she looked up and waved (in reality, at the friend who walked behind him).  What happened next will happen to everyone at least once in their life, by unfortunate fault of human eyesight.  He hesitated for a moment, but waved with an awkward half movement.  

She almost laughed before looking firmly past him apologetically, to clear up any misunderstanding.  He passed by, then, looking once again at his muddy shoes.  (Can’t Go Back Now from Hideaway)

Well, it’s The Weepies
