My aunt last week said
"oh well you'll be able to go to restaurants- do lots of eating out - tha'll be nice".
I explained there was no way we could go to a restaurant with ds1.
"Oh but your mum said he was getting better since he's been at his new school".
WTF????? So then had to explain that she meant that he was improving a lot, and was a lot happpier, but was still miles away from normal and always will be. And that restaurants didn't feature.
I've had the "oh he doesn't look autistic" one RnB and the sppecial skill - usually oh "I bet he's really good at maths isn't he?". Talk about not having a clue.
