Im gunna respond to this thread on a more superficial level at first - to me a 'poser' usually refers to how you present yourself/appear in photos etc. I have to strike a certain 'pose' in photos because the camera doesn't love me and i only end up hating the camera unless i put a little bit of effort into it. On a deeper level, my sense of self is usually highly disturbed by the disorder i have - i used to wear identities like hats growing up...i was the Madonna of high school. I feel much more settled now - i suppose a lot of it has do with age as well. In terms of people im usually reserved and occasionally abrupt with those i don't know but can go the complete opposite with those i know well i.e. very hyper and talkative. I guess i don't present an image of myself that im not because in truth i don't quite know who i am - at least not fully. Sorry if this response wasn't quite what you were looking for.
