Model: triangle relationships
December 19th, 2020
I don't remember exactly, but it goes something like:
The third person is responsible for resolving conflicts between 2 people.
Like when you hear 2 of your friends are fighting, it's your responsibility to mediate.
And I remember vaguely something about 'triangles being a stable form' in nature, used as an argument or something.
