From the communal ovens of europe:
“These common ovens also encouraged diversity for the “loaves going into the oven were slashed with distinct patterns so each family got back its own–really its own, since the grain from which it was made was grown on their farm.” via IDFuel
This makes me think about the power of diversity in communal sharing and the power of the unique results that could come out of sharing an object with particular people. How would an object react to whether you use it with you girlfriend versus using it with your friends.
