i know it's only one of many possible layers to analyze.
so far i've picked up fairness, justice, responsibility, and trust. so/sps seem like they want to become a perfect person (as defined by ethical standards, not a burden to others, steady, and foundational for those they care about).
they are indirect and at times have trouble initiating direct contact with others. not just in an introverted way, but more so in a friendly with everyone but having trouble communicating deepest recognition with specific others. at times i imagine someone is talking to them, and will say something like "are you even listening," because they are looking away. but the so/sp usually is, is generally very considerate and generous in spirit towards others.
they are less willful; what they want is less important than what is right. generally open and trusting but needing time alone to get away from human affairs and expectations of others, who always seem to want more.
does this seem right? what else should be pointed out? i ask partly bc i've had a lot of great relationships with so/sps in the course of my life. i think as /sps they have a tendency to appreciate, in solitude, the value of their relationships and be more consistent in renewing them. their generosity and overall friendliness has at times helped take the edge off of me when i was more socially acerbic and clueless. i value their steadying influence and deeply-rooted ethical example and they value my ability/desire to draw them out completely/try to recognize the whole of them.
