I think we are being unfair.
SOME ASD children are very self-centred, quite narcisstic really, and often if a world of their own, that is very difficult to relate to, connect emotionally, enjoy that closeness that many of us crave, but some ASD children do not quite have that need.
So some parents find you give, give, give but get little back in return. AND that's hard. Imagine THAT thread. hashtag, just saying!!
Now we accept this, that is can be symptoms of ASD.
But, stop for a second, if the child wasn't ASD, and had those traits, were just self-centred and narissitic, the parents might be on a different section of MN asking for help/guidance/just having a moan about how their parent/brother/husband/child/ex is completely narcissistic and uncaring.
There would/could be a double standard to maybe some of the responses these 2 very different threads would receive, don't you think?
