A Scratching Done Under The Surface

It is foolish for anyone to perceive,
And believe...
They can approach others,
With the notion they can teach lessons...
Without knowing the experience,
Or a past history just by observing one's 'cover'.

A scratching done under the surface.
Or at least some knowledge of what one knows,
Will save another from embarrassment.
And a cold shoulder one unintentionally...
Shows without a doubt,
Can and will be exposed
