Dear Conrad,
I much prefer looking at old episodes of cowboys on the telly.As far as gazing intently at someone, this can and often results in a confrontation.In general I like to have eyes / look that appears benevolent [and 99% ]of the time is a benevelent gaze.It is only when the chips are down and the situation is serious do I become a little bit more intimidating.I believe you can train to swich on and off how you project your demeanour.
I have met doormen , loan sharl enforcers in my day.Socially they were goodd guys, happy smiling eyes , quite witty.Totally opposite when they put on their Mr Nasty hat.You knew when they were up for it ,and willing to exchange blows.
I think a apparent pleasant manner can get you out of a sticky position, and if not thats too bad. Cheers, Joe
