My son was diagnosed with Aspergers recently and although he has made some progress I am finding it a little difficult as we live overseas and there is little support here so I am learning very quickly from books and websites. I understand that role play is useful to encourage him to develop empathy and I have tried to do this whenever he has had a negative experience (e.g. a disagreement with a friend). One problem, however, is that occasionally when I have said "How do you think your friend felt when you shouted at him?" he has just denied that anything happened. How can I take the conversation forward if he insists there is no issue to address?
