Okay, having dumped satisfactorily on the stupid initial quite, maybe it's worthwhile mining it for the kernel of truth it holds.
"Predator" is maybe wrong. But in a physical encounter, on the mat or off, you can't be tentative. You can't see what happens. You have to be absolutely without doubt that, whatever happens to the other guy, you're going to be on your feet at the end.
Or maybe whatever happens in the end we're both gonna be o.k.
