Can you pick up on other peoples feelings? Well, yes, if I manage to dodge the first brick then I'm aware they're pissed off.
They are difficult questions to answer with any degree of objectivity or accuracy though. I found myself more-or-less guessing at answers because I genuinely had no idea if other folk where more or less x than I, and so I can't honestly judge my levels. Equally, I change. I can be more x at some times that at others. Sometimes I decide to listen, sometimes I switch off. How do I gauge my average/median/whatever level?
It's simply easier to say I'm an arse! Or a saint, whatever.
