People always think I look so serious/sad/depressed/angry, that I've been quarreling with someone or something like that.. when I actually look neutral and am definitely not in a bad mood. Sometimes it can upset me and when I ask "why do you say this?" or "why do you think so?", they always reply that it looks obvious on my face. So as a conclusion, something is really wrong with my face expressing what I really feel. Now at least I know that it's part of the syndrome, before I asked myself 10 000 questions, tried to "change" or "fit" and I was pretty tired mentally.
About the pictures, I have always hated to be forced to smile. Seriously, why should we smile on pictures ? Can't we appear just neutral ? or must we pretend ? I hate that acting thing.
Of course when I was forced to smile the result was pretty bad and I looked like everything but my real self, which was very funny for my (stupid) friends at that time, always making fun about my weird faces. I will never forget their big silence after watching a picture in which I appeared and then their "mmm we can take another one". After taking the second picture, same silence and then "mmm let's say it's fine". Really, I don't know how to act in group pictures or even with just a friend, I don't know what to do with my eyes (+ I'm quite photosensitive so I often end up with my eyes closed), where to look, smile or not, be near the person or not, hug or not... ?!?
I tried "photo-modelling" as an exercise and paradoxically it went ok. I think the fact that it was pure acting wasn't revealing my issues. Well, I don't know, I just suppose.
And finally when I take pictures myself for profiles pictures for example, people always tells me that I look sad, or that I have a weird look (like very big eyes), a strange smile if I try to smile - and I think I look ok.
When I post a picture in which I think I appear silly (with weird look, smile, attitude etc), people like it. NT's are very confusing ! =)
