You and You ...

Sometimes I get tired of
self-proclaimed heros
Bombarding me with 'wisdom' and 'insight'
About the me they think I am

Don't bother to examine
the plank in your eye before you point out
the specks you see in mine.
I am well aware of the things that obscure my vision

And all I want to ask is this:
When was the last time your radar
accurately picked up the signals
I am sending off?
