Not so much out in the real world, though I'm sometimes surprised by how much other people notice - about me or about others.
I sometimes I wonder if someone will be following what I'm writing on the Internet. In one sense I am very open, maybe too open, on facebook and twitter - using my real name. I sometimes wonder about people from different areas of my life reading my opinions on there! Future potential employers? Old teachers? My T? My PARENTS?!

Sometimes I think I should use a fake name, but paradoxically I want people to know who I am... I wish to be seen as 'authentic' and 'real'...
What sometimes concerns me even more is if someone I know IRL were to somehow find me and follow what I write here or elsewhere under a 'handle', just because it's in some cases very personal information that I wouldn't necessarily share with people I know - because I'm not sure they would understand. Then I tell myself to get over it -- what possible motivation would someone have for scouring the internet to find out what I think about therapy or whatever? I'm just not that important! People are busy with their own lives! I guess my only semi-legitimate concern in this area is if my therapist happened to visit the site and stumbled across a post and recognised me. But again, I'm sure she has better things to do than puzzle over forum posts trying to find her clients. And then again, I doubt I share anything here that she doesn't know already.
Paranoia strikes sometimes, though!
But then, sometimes I get curious about things, about people... is it so crazy to think maybe someday someone may be curious about me? Sometimes I google my own name to make sure nothing too embarrassing shows up!
PS: Had to lol a bit at the 'Joyce' story! Cringe! I don't really have neighbours here, but when I lived at my mum's house for a bit I was VERY aware of the neighbours noticing my comings and goings - when my mum was away I knew it would get back to her if I had friends over. Ugh, living in a small town didn't go down well with me, I just thought that some people needed to mind their own business!
