When normally you don't really notice?
Cos it was my eldest's review the other day. And he is now in secondary school and at his school (don't know if it is the same everywhere) they have the child in the review and begin to encourage the child to take control of the review.
And I was looking at him as he went through a statement he had prepared about things he finds difficult, and his eye contact was non-existant and he had one arm in the air, making a pincer type movement with his fingers.
And I looked at him and I thought wow, you really look autistic.
And I hope I am explaining myself well 
It was just a real jolt, you know?
Do you ever have it?
