My job is a bizarre mix of independent solo working within a very social-interaction based environment. This can be really quite draining sometimes and days by the time I make it home I'm so mentally drained its all I can do to function long enough to make/eat dinner.
I've had to develop a few strategies for coping with my work environment, one of the strongest ones in my armoury being my ability to fake interest in a topic being discussed around me.
I try not to utilise this too often as I don't like presenting a fake front to anyone really, but there are times I genuinely don't care about someone's son's girlfriend or the latest soap plot but I recognise that its not a situation I can politely escape from any time soon!
Over the years I've asked trusted family members and friends to let me know of the 'tells' I display when I'm starting to grow bored or irritated so I can try to keep them under wraps when need be - of course this doesn't always work and there have been many times I've utterly failed at keeping my internal thoughts from shining through my body language, still, I like to think the rates are improving!
The main thing I've found is that I have started to recognise when other 'normal' people are doing this around me as well, I wonder just how much of human interaction is made up of faked interest to conform to what we believe social expectations are?
