I suspect that my having trouble with reading this particular person is partially exactly [I]because[/I] she tends to be... I don't even know how to describe her. Overly genuine? For whatever reason, I - at least during times when she's not withdrawn and doesn't really pay attention to anything going on outside her own head - just have to consciously observe her to notify myself how she's feeling/what she's thinking... I guess her expression/tone tends to come off in a way that I instinctively interpret as exaggerated and therefore tend to think means the opposite; that she's being sarcastic, in other words, or trying to hide how she really feels. I have [i]learned[/i] to read her, but somehow it just isn't as intuitive for me to read her.
Another possible reason that I find her hard to read - and that she tends to miss hints at what others feel - is that she often forgets to actually look at the person she's talking to. It's not that she's disinterested - definitely not indifferent! - just that she tends to get deeply absorbed in whatever she's doing at the time. Even then she will pick up on how one sounds, if one's voice betrays emotion of some kind... eh, I didn't mean to say that she [i]can't[/i] read people, nor that she doesn't want to, just that she often, eh... forgets.
A autistic sociopath, though... hmm. I wonder if such would have more of a tendency towards indifference towards other people than those who possess just one of the traits?

The trend in modern society to want to "fix" people like that is worrying though, I'll say that. Even people with relatively minor "disorders" gets handed psychiatric drugs as though it was candy. And while that is worrying in and by itself - especially considering the [i]catastrophic[/i] side-effects some of those drugs can have, and just generally have effects more disruptive than the disorders themselves - I'm also pretty concerned with how eager doctors and psychologists are to diagnose people with all kinds of things. I don't know if that's a general trend or specific to Denmark, to be fair, but I know that here doctors have become especially keen on diagnosing everyone they can get away with doing so with ADHD.
Eh... yeah. Some things are just better left alone, and many things pushed aside and forgotten through the use of drugs are things that would be [i]far[/i] healthier to work through without them. I could go on about painkillers too, but I'd doubtlessly be unusually biased about those considering my own insistence on not using them despite, you know, being in constant pain and all that.
...How did we get here?
