To be honest, the best thing you can do is ask either them, or their parent/carer if they have one..everyone's different, some things that will help one person with autism might be a trigger for others. Edit: I'm assuming high functioning if he's doing Karate, but that probably means "moderate" on the social aspects..which quite possibly means he'll have someone there with him; I'd just ask them for any special treatment he needs, things to avoid, things he'll respond well to etc. Good luck :) Edit2: re-read it and realised how tired I was when I wrote it, so fixed some spelling for you..incase you're as OCD about it as I can be.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
