You've got it all wrong.
It has nothing to do with me my dear.
I'm not speaking of some great, soul-searching mystery like:
Who am I? or Why am I here?
Rather, it has to do with you.
Why, why, why
By a river on a cold early evening,
In autumn-heavy, dull-dark air,
At that exact moment at that exact hour of that specific day...
Why were you exactly there?
I know it is a mystery but still I think the question fair.
