Reverse Vampires

Some people who live alone
act like reverse vampires.
They suck the bloody life
out of their co-workers by day --
demanding and commanding the attention of their colleagues,
holding court by holding folks hostage,
unloading their every thought and question and concern on people
like a dump truck possessed of the devil --
and retreat to their solitary homes alone at night,
lying in wait for the sun to come up again
and provide them with fresh blood
to live another day.
