shame caution

Shamelessness is dangerous.
That aimless inhibition prompt 
lays snares of consequence and guilt
to trip us, everywhere we'd want 
to take our valor for a spin - 
and leave discretion's bare, bereft
behind at home! A-wallowing. 
For shame! Best be behaviorless,
lest valor's indiscretion wrest
some veil aside, and all be known. 
We'd never rest from labors, then. 
To soak and scrub escutcheon clean 
- a labor which we know is vain!
But that is how we've always been, 
to our acute and chronic shame.
