Rumi speaking to a crowd muses:
Watch out for those blood suckers from hell —
cause they’re everywhere.
And the crowd wisely retorts:
“That sounds serious –what do they look like, any hints;
are they usually disguised?”
Rumi again: Yes, usually, they are awful tricky!
“How then to detect them?”
I have noticed
their eyes will narrow and their faces begin to squint
if they hear good poetry.
