Much has been made in the literature about the rigidity of the Aspie. A good example of this is their "resistance to change". Often the observed behavior isn't a resistance to change, but a binding to a particular rule or rule set. The aspie is, to a certain extent, controlled by rules. The impact of these invisible rules on their behavior should not be underestimated. It is often a source of conflict and can also be the source of aspie depression. Where do these Rules come from? The majority of the aspie's rules come from their own environment. They can be communicated directly or implied. In some cases, the aspie will completely misunderstand directions and create an internal rule that isn't necessarily in their best interests. Changing these rules is difficult, especially when they've been in force for an extended period. An example When I was quite young, a grandparent saw a boy give me a "suck" on his chupa-chop (a lolly on a stick).
