Wicked Puppy

A description of what I did to a friend.

Such a vile creature I am.
The warmth and compassion having long ago faded from this heart of mine.
I sit in waiting for the next victim to arrive, to take pity upon a worthless beast.
They pet and hold, love and care.
Still, I lunge for the throat, cling tightly, awaiting for the final breaths of air to bubble from their lips.
My last victim still twitches, she called me her 'Wicked Puppy.'
