Sparks.. do they even exist?

What I want to highlight with this post are the sparks between two people. What is a spark? A spark is the moment when you meet a person for the first time and have a different feeling, a feeling of joy. Maybe I am wrong but that is my personal opinion on the subject. Nevertheless I found myself in different situations when I had encountered this so called "spark" when meeting a new person and most of the time something more then a mere friendship happened between me and the person in question. Sometimes it was a serious relationship , other times just a few months of tease and in some isolated cases some night you can never forget.Then the question arises why do I question the existence of this spark? Because I found this spark to be wrong in most cases .I would only say that a spark happened when it only represents the messenger of fate that the person you meet will make you happy if you pursue her.But life is never so easy and simple..and the spark sometimes is wrong.In the end throughout our lives we will encounter many "sparks" but it is our job to know when to pursue it and when to just let it go...
