I've been thinking about this discussion some more and want to throw in a few questions if anyone wants to answer them.
Before this, can I just say that I do see what you mean, jimjams and davros, about friendships based on shared experiences and, as a parent of an autistic child, you just don't have the same experiences of parenting as NT parents.
And I do realise, and perhaps my last post didn't make it clear, that in reality you wouldn't automatically blank all NT parents (because you are a reasonable person) but you'd proceed with a low expectation of friendship.
From my point of view, I think autismn is an extremely tricky condition for an outsider like me to understand. Even reading messages that have been posted on threads by you and others, I still feel mystified. If someone asked me, I couldn't give a full discription of autistic behaviour. Whatever I said I feel would be based on wrong assumptions. When I read your posts and others they are very illuminating but ahhh... I don't have enough computer time to read more than a fraction of them.
I have some second hand knowledge of the pressures of caring. My mother looked after my father, with assessments, respite care, many frustrations and instances of wrong diagnosis. I grew up watching the stress she was under at times, and seeing her get on with it too, knowing that that her daily life revolved around my father's needs, things like him having to have a poached egg on toast at 4.00pm every single day. It didn't make always sense to outsiders (why couldn't she just say 'no' for once) and to be honest it didn't always make sense to me, a teenager, though that was my failing, not hers. Anyway I'm rambling.
First question, addressed to no one SN parent in particular: do you think you will have the same resigned attitude about mixing with NT parents in 5 or 10 years time? Do you know many parents with older SN children, do they belong to your groups, how do they find this divide? Do you think it gets any easier to find some common ground as time goes by?
Also, coming back to ages 3/4/5, I'd hazard a guess that quite a few parents of apparently normal children do not take that normality for granted, do not really know if their child is 'normal', worry that their child will not fit in academically or behaviourwise at school. I know I am in that position with my youngest son. OK I can present a fully potty trained, talking child to the reception teacher, so I can't pretend to have your experience jimjams, but I still am not sure (and others have real doubts) that he will be in the 'normal' range. I know this probably sounds like that parent of a dyslexic moaning to you about problems you can't feel deep sympathy with, but my point is that many parents out there don't feel their child is totally NT and surely having that doubt in itself brings some empathy.
Last thing, I do wish I'd spoken for longer with the woman with autistic sons that I met on the ferry. When I asked her if she belonged to any local autistic groups, she said, very firmly that didn't believe in that. She didn't want to get into the whole internet, group meetup thing. She'd didn't want to mix with people just because their children were autistic. But I didn't ask her why exactly......... if only she was here to elaborate.
