Something unknown
Something unspoken
Something incomprehensible
A mysterious entity it is
Chasing it is like
Catching a cloud in the sky
Grasping it is like
Finding the end of the rainbow
Everybody must have it
But nobody has ever seen it
Everybody talks about it
But nobody can explain it
Common sense, are you there?
Your presence is requested
It is time you come out of the dark
And clear your mess of uncertainty
