there is a balance here with Seeing friends only at social events is a bad equilibrium
synthesis is something like - casual social interactions as a part of larger group are good esp in the beginning as you are discovering the other person
then you can introduce more 1-1/small group interactions
but have a larger social group interactions as a way to mix things up/discover new aspects of your relationships
Plausibly also hosting things where I invite people I want and curate the experience is also a part of the synthesis
