When and then was great cause ADHD and odd prevents them from doing anything that they have not thought of on their own terms . In there own head . So when and then gives them the security that what they want to do . Is in they near future if the complete what's asked .
I use reverse psychology... cause odd is the opposite of what u say .. they want to do the opposite. So I say what I dont want them to do but ask as if I wanted them to it and he ends up doing what I want .
