the one that got away

so, as i've mentioned, i'm working on a new project, a romance that revolves around catching the uncatchable.  in this particular case, i was inspired by the concept of the one that got away. 

we've all got one of these--the boy in our college chem lab with the great smile who seemed the perfect catch, but whom we could never quite muster the courage to speak to; the girl in high school we dreamed of but who never quite noticed us; the boyfriend who dumped us because he just couldn't commit; the girl who we dumped because we were just plain dumb.  The ones that got away. The ones that might have been. 
Now, that's not to say that we didn't turn out just fine--in many cases, we crawled into the tall grass, licked our wounds and then, several days and far too many pints of coconut sorbet later, we rose again to meet the world--and the next one.  Who maybe, just maybe, turned out to be The One...not just the one that got away.
But the project I'm working on explores the age old question: "What if the one that got away was The One?"  And, more than that, "What if we got another chance?"  
My heroine, Callie, is in this very dilemma.  She's been in love with that proverbial guy from chem lab for her entire life (if they had chem labs in regency england--or if women went to college in regency england--this metaphor would be perfect, but just go with it).  And now, it's her 10 year college reunion, and she's got her chance.  He's still single.  She's still single.  But how does she get him to notice her now that she's a decade older and a decade shyer--and he's a decade darker?  Here's her chance to finally catch the one that got away...but how?  Especially when he's so very handsome and she's so very...well...plain. 
And that's the premise of the love story I'm working on. 
I should say that I actually caught the one that got away, so this is a premise that's rather near and dear to my heart.  But Callie's story is far more exciting than my own.  At least, it's shaping up to be.  
Now it's your turn...do you have a one that got away story?  willing to share?
