bad case of ex-factor

what is it with exes that we just can't seem to get rid of from that tiny corners of our minds? come on, don't lie, even the oldest most forgetable ones are not really as forgetable as they seem.
even when you consider yourself settled, matured and far beyond conscious that those stupid things you did when you were fourteen are-finally!-something you can admit of doing they would come crawling the from behind your skulls and into your unconscious-or in some cases- conscious mind. i mean, what the hell went wrong there? was it something that we forgot to do when we said our final words? did we forget to say something that they were expecting us to say on that fateful day when we stated 'goodbye'? was it "sorry"? i am sure i've said that, then was it "i loved you"? wouldnt i be lying if i'd said that? then,..what was so wrong about what i did to make them continously haunting the edges of my brains like an over-determined undead? did we-in that short time in being together-ever connected in some ways that our minds somehow find the ability to relate with each other's brainwaves?
i guess exes are like a bad case of blisters that you get from your new shoes. instead of pretending tehy weren't there by covering them with band-aids, we should just accept the fact that even time isn't enough to heal this sort of wounds, it will still leave a distinguishable mark, no matter what you do. so the best that you can do is to reconcile to the fact that it is there, and you just have to accept the fact that despite the fact that some exes are rather forgotten than forgiven you just cannot deny the other unrecognizable fact that they had also been a part of your life's history, the ones who would also think of you when you're gone, the ones who would still remember your birthdays even when they pretend they forget, the ones who would sometime go silent in the thought of your whereabouts.....but then, like those blisters, if you still haven't figure out how to get into those shoes without giving you blisters, then trash it, girl, and get yourself new ones...if the new ones do the same to your feet, then it should be said that the two of you dont match, and you should re-embark your soul to the long yet winding search for the new blister-free shoes
