A dash of emotional could force a displacement.
A pinch of physical could touch
off a combination.
A hint of intellect might spark
an exchange.
What catalyst is left?
As the rate of reaction nears zero,
there's no substance to reconnect the bonds.
Like Bokov I remain awake, pondering
the chain of events that would lead
to the perfect covalence.
