'Yes, I know'

Its strange how often the phrase is used.
But the ease with which it is said, heard, repeated and accepted as a statement is fairly alarming.
The sheer limitation of the human faculty to comprehend complexities that are intrinsic to our existence stares shamelessly in the face each time the phrase is mentioned.
Knowing is a very gradual process. At an age when a sizable chunk of people can be found grappling with grades, targets, parents, managers, women and other terrifying issues, its a pretty tall claim to say 'Yes, I know.'  
Existentially speaking, its actually quite 'absurd'!
