Firstly, thank you for not having the God complex, y'know when medical/psychological practitioner assume that they are omnipotent and omniscient and are all knowing...
Lots of Aspies are quite insightful. After the event. I don't know if you're familiar with something called 'fuzzy logic'. Lots of Aspies don't have an inherent ability to 'know' or 'do' something, but they can learn through experience.
We are all different. Personally, I tend to understand obvious idiomatic speech isn't really 'real', but I do take lots of things literally, so I can come across as quite gullible and naive.
I'm not particularly monotonous in terms of tone of voice, so I can pass relatively easy for NeuroTypical (NT), but I do still struggle in terms of body language, nuance and understanding other people's tone of voice.
In terms of facial expressions, I have a kind of face blindness in that I'm not very good at recognising people in a different context. For example, I bump into someone in the street or at a train station and I know I've seen them somewhere before, but I can't remember if I it's a friend of a friend who I was introduced to over coffee or at a party, or whether it's the checkout girl from the supermarket. Because I can't place people, sometimes I ignore them, in case I greet the supermarket checkout girl like a longlost friend. So people can think I'm a bit 'off'.
I can learn things though, like body language. I failed an interview years ago and a colleague gave me a book about interview skills and I read about body language in interviews, firm handshake, gain and maintain eye contact (but don't stare!), etc. I also learned a lot about body language from a personal perspective from women's magazines, the advice columns, 'how can i tell if he fancies me?' kind of stuff, plus a television programme about dating in the UK on BBC2 called "Would like to meet" which had a woman presenter giving flirting advice, lessons in how to read body language, that was great. If I actively *learn* something, then I can put it into practice, but I don't naturally have those skills.
I'm one of those Aspies who is quite self-aware and insightful. I do like to socialise, but I do still find it hard to make and retain friends.
"At this age would you want help to understand people better or would you not know what the therapist was talking about when she stated that it is harder for you to understand others' emotions and thoughts? I am just wondering if the kids will get the aim of what I am trying to do...or if they will wonder what on earth I am trying to teach them and why do they have to learn it? I really want to do my best for these children...Please help me..."
Oh, they will probably understand and appreciate what you are trying to do. Aspies tend to be quite logical, so if you explain stuff in logical terms it can and will sink in. I think probably most teenagers want to fit in better, even those non-Aspies who are a bit different, in whatever way, because peer pressure can be a terrible thing.
To just explain what other people do, and what they mean, will unlock so many doors and make life so much easier. I wish I'd had the same opportunity and the same help when I was 12.
