The Barking Mutt

They know what they know
and they know that they know
and heaven forfend what they know
be challenged. So none do. Once is
always enough. They, on the other
hand, scenting opportunity
make hast to challenge the
stated opinions of others with
the effluvium of their superior 
knowledge, brooking no response 
as legitimate, making it quite 
clear that the last word will always 
be theirs. Somewhat like annoying 
little dogs with their size-related 
inferiority complexes that 
surface reflexively as belligerent
appraisals expressed in snarls.
The little dogs' behaviour merit 
pointed and gentle discipline. The 
sniffing last-worders, icy silence.
