It's a Tuft War

It’s the way of the world

When there’s two of a kind

It’s a duplicate of sorts

It would be just fine

If they can find their own tufts

But as always the case

It’s space and acting terse

Instinct determines the pace

Just a quibble and they erupt

They take positions aggressively

The equation is quick to disrupt

They bite lash and gnarled incessantly

They just go berserk without warning

Like the dog in the manger reacting

Not unlike a human provoked parrying

Off blows after blows contending

Each having as much rights

To wrench away at victory

Insisting to resolve to fight

To retain a semblance of authority

Written for 3WW with words berserk duplicate and quibble
