A gun most definitely. Pointing at him for a long time and him knowing it. No words needed.

The power of the trigger is with me and I savour it. Until I start pulling it towards me.

Its done, the first mark is made. The first of several. Legs. Hands. Genitals. Before I no longer want to be near him and I give him one final mark in the mouth.

And I walk away, having transferred anger and disgust and fear to him.
