At some point, maybe at most points, simply walking away and disengaging is not a bad idea. Minding, though, that strategy may have to be backed-up with effective and concerted self-defense if the Neanderthal(s) in question decide to respond to that attempted disengagement by pursuit.

Hope I am making some sense; words are not coming easily today, which is a pity because this has been a subject of great personal significance over the years.
