These two have very different lifestyles and goals. What the Sun person is seems counter to what the Saturn person sees as right or correct. Strong judgments about each other can come from this aspect. The lifestyle of the Saturn person and the personality style of the Sun person don’t get each other, there is very little understanding in the way of appreciating each other’s goals and sense of accomplishment.
Social issues and politics can be an area of disagreement. The moralistic structures that the Saturn person holds dear and the behaviors and attitudes of the sun person are not in agreement so the Saturn person can have some judgments about the Sun person that come from a place of rightness or a superior understanding. This can lead to arguments and disagreements that revolve around culture and the laws that govern behavior.
This can be a minor aspect between two people if we see other aspects that provide compatibility, especially a good aspect between the Suns or good agreement between the Sun or Saturn to the midheaven of the other.
