An excerpt from Parenting Your Asperger Child by Sohn and Grayson:
He thinks that his opinion is as good as yours, so he chooses his. This represents his rigid thinking. He finds it difficult to be flexible and consider alternate views, especially if he has already reached a conclusion. New ideas can be difficult to accept ("I'd rather do it the way I've always done it"). Being forced to think differently can cause a lot of anxiety.
How many times, in the church world, have I heard the phrase, "But we've never done it that way before."
