I'm not a parent, but the main reason why I'm putting this in the parents' forum is because I am curious about one thing. If you and your aspie child were in a store, and there were huge ceiling vents in there, and your aspie child started staring up at the vents continuously, enough so that he is un aware that he may bump into somebody, what would you do? I am curious, and, being an aspie, slightly obsessed.
