And with this Substitute's amendment of 'polite and friendly are enough' -- I think this actually will make someone safe and socially acceptable. Like how you describe the shyest kids in highschool as 'nice' because you know so little about them (and have not had the inclination to change that) you have nothing else to say about them.
I remember the ONE person on my team in my last job that I actually could stand, and that was exactly why. He was polite. Actually he wasn't even friendly, he was NEUTRAL which comparatively in tank of sharks might as well be friendly.
Basically, I have to rethink what makes someone 'likeable'. I guess I'm not sure about the definitions. 'Likeable' can mean don't rock the boat and kinda boring...which is exactly what people go for in certain job and work situations. Pleasantly safe.
I guess if you were enthusiastically and genuinely friendly that would push someone past 'safe and bland' to having a likeable quality.
At least this is what is going through my mind right now.
