Oh god yes.
I think it's the sort of rose-tinted 'awww, what a saint, but you're only given the problems in life you can handle' sort of attitude that drives many many parents of children with SEND to despair and sadly, often beyond that. People certainly romanticise autism (if they have no direct experience, or have only met people who are, for want of a better term, higher-functioning). I get sick to the back teeth of being told that my son probably has a hidden superpower, or 'I bet he's really brilliant at maths, isn't he?' (he might be, I doubt it, but his autism means he's not remotely interested in showing us. He can count up to and back from 100 if started off. he's 14) or that 'it must be so rewarding'. No it fucking isn't. DH and I are knackered, constantly battle-ready, depressed and looking towards the future, when he has to leave 'child services', with dread. No retirement for us.
