So I just read SouthNarcs essay on unknown contacts. Excellent read and very well presented, one thing really struck me though, the grooming cue. I have never had any training on body language, but working in bars for many years I thought I had a good handle on reading it. Man how did I miss this particular piece of info? Looking back at any of the fights or near fights that I can remember, almost every time the shithead did this. SN gives a simple explanation for it, but I'm wondering if anyone (SN included) has more to offer on this cue?
