Identity

Who am I
Lets see!! Alot of identiy cards I have. Looks not difficult to define this simple thing.

Am I professional engineer (Hmmm so It means I didn't exist before 4 years)
Am I employer of Comsats university (Hmmm before few days I was emplyer of Gujrat University)
Was I student of Magdeburg university (Then why the card is not valid now)
Account holder of Meezan bank, Citibabank or The bank of Punjab (Then how can they expire account on withdrawing money)
Am I Pakistani (What would I be if born before 60 years)
Am I Faizan (Come on! there will be 1000s names like this)

Who am I. This thought has sorrounded me and makes me think. Maybe what I think defines what am I.
