Our grandson, who is nearly 18, went to a primary school, but his parents thought he would be better home schooled for his secondary education. He was so much brighter than the other pupils and was teased because of it. He got his GCSEs well before he was 16 with mostly A*s. His mother suggested he did his A levels at a college as she was unable to assist with the subjects he wished to take, but he decided he would teach himself, which he is more than capable of doing. He is obsessive about trains and takes himself off on them all over the country and recently to Europe. He is still not entirely sure what he wishes to do when he finishes his schooling, but will take a year out in the US before going to uni.
My husband gets on extremely well with our grandson as they see things the same way. They never chat, they have debates, where they each provide evidence to support their POV. I leave them to get on with it as it is well above my poor little brain cell's capability.
When I was young, autism was not something that most people had ever heard of. When I first met my husband I thought he was very different to the other lads I had met, they were boring in comparison. He and his best friend, who mostly likely has Asperger's too, spent a lot of time creating circuit diagrams, with which they appeared to be obsessed. My husband rewired houses to help pay his way through university, and his best buddy was a top rocket battery designer at ESA. My husband can't be tested to see if he definitely has the condition due to the serious brain damage he has sustained, but I don't think there is much he has it. He says he liked being the way he was before his brain haemorrhage deprived him of half his brain.
