Obstruction
 
What is said should unsaid,
What is done should be undone.
What I said I never did,
Is what I never did say.
For one should not forget,
What one will not recall.
And those that will decay,
Will change their view forever.
While those that last on always,
Sit with mind set in stone.
Never will it happen,
For always it has come.
Always it will avoid,
For never has it been.
