What draws them together
Why they are drawn to each other at first
The Adapter feels reassured by the Crafter, who stays the same wherever they are. The Crafter has plenty of the consistent manner the Adapter lacks.
The Crafter, in turn, is drawn to the flexible Adapter, who fits in naturally anywhere. As the Crafter sees it, the Adapter gets along easily even in places that do not match the Crafter's own standards.
Where it goes wrong
One asks for the real person, the other gives what fits
The deepest conflict between them is over sincerity. The Crafter asks to see the person as they really are, and the Adapter shows whatever the other seems likely to want. The Crafter feels that this is put on, and the Adapter does not understand why candor matters that much.
The Crafter's strict standards make the conflict bigger. When the Crafter, who wants to finish one thing completely, is exacting, the Adapter, who shows a different side in each situation, takes it as a demand that is hard to bear. In turn, the Crafter sees the Adapter's many sides as a lack of depth.
The cycle that wears them out
How each misunderstanding produces the next
The more the Crafter doubts the Adapter's sincerity, the harder the Adapter tries to fit in, and the more the Adapter fits in, the more the Crafter doubts their sincerity. Both keep repeating a pattern in which what each does to reassure the other only makes them trust each other less.
If this goes on, the Adapter gradually loses their true self, and the Crafter grows lonely because they never come to trust the person beside them. Neither means any harm, yet both wear out together.
Still · what they can learn
What each can learn from the other
Paradoxically, the two can also become the people each other needs most. Beside the Crafter, the Adapter sets their own standard for the first time, and beside the Adapter, the Crafter learns to express their true self in more than one way.
Showing many sides and keeping one's true self are not, in the first place, opposites. When the Adapter stays flexible yet acts consistently and the Crafter keeps their standards yet becomes more generous, the two can learn what they lack from the very differences that used to wear them out.
