Rex,
Regarding association classes, they are "bidirectional" because -- deeper
down -- an association class is a class that is associated with two other
classes in a specific manner. See attached ppt.

> Trust: Trust is an actor's private perception of the commitment

> Risk: Risk an an actor's private perception that another actor's

> What I suggest: Trust is an actor's private perception that another
