Points where to be careful

The greatest potential problem in this relationship is about authority, because both types adapt easily and someone needs to take a decision. This will often be 2, but not always, and 9 will struggle to make himself heard. With time, 2 can even become rather dominating and attempt to control 9. 9 will respond to this with stubborn resistance, often in the shape of passive aggressiveness.
