I see you. I see you clearly. I may not react to you instantly, but I do see you.
You are a fool. A fucking fool.
I may be carrying a weapon myself, and it may be one that can be plunged into you or discharged instantly. If I decide to do so, rest assured that it will be done with skill. I will do not do it for fun, or theatrical effect. I will do it to kill you quickly.
This is not television. The cameras are not on.
Note – if I am not carrying a weapon right now, I can go get one. It may be physical or virtual – but it will be real. And as you have shown that you mean me harm, the rules of engagement are already set. Run, and do not look back.
