Quickly deciding that my annoyance in having my meal stolen and enjoyed by a mere ghoul again is far bigger and worse than having to help the human out this single time I take action and, while the ghoul goes to take another bite, I aim and kick a stone that was laying beside me with strength, making it fly up and hit the head of the creature with a bang.
I have to control myself and the amount of force used since I did not want to blow my cover of 'fragile little human' up, but I still somewhat managed to miscalculate the amount of force I should use to appear human, or rather, the lack of force on the rock, and as result instead of only stunning the ghoul the projectile manages to make the creature fall on its back towards the ground, a deep hit on the side of the skull where the rock had imbedded itself, still there, which far from simply disorientating had almost been deadly.
