Dracula stood pacing at the gate…
“My friend, my friend, you have arrived so late!”
“So sorry, so sorry, please do forgive. Now what is it you want, so I can live?”
“Please, oh please, more blood, more blood, yours so fine: Loving, intoxicating, like a Merlot wine.”
“In return, my dear Dracula, what will you have for me where is my reward promised in the hours so wee?”
“The reward, your reward are nuggets of gold, those heartfelt words I occasionally unfold.” The nuggets of gold, the spices of life, the times when I help you in strife that is your reward for giving me life.”
“Dear Dracula, Dracula
that is not enough.
I know your thirst, I know your hunger pain,
I wish I could help with my heart and my vein.”
“But the clock is a ticking, ticktock it calls, my time so precious; I can hear the footfalls.”
“So Dracula, Dracula Adieu, my dear friend I bid you a source of blood so sweet, your ravenous hunger, it will finally deplete.”
Dracula can be a metaphor for anything, bounded or unbounded, that sucks our life blood from us.
