In the Neolithic megasite at Çatalhöyük families lived side by side in conjoined dwellings, like a pueblo. It can be assumed that people were always in and out of each others' houses – in this case via the roof. Social mechanisms were needed to make all this run smoothly, and in a tour-de-force of botanical, faunal and spatial analysis the authors show how it worked. Families stored their own produce of grain, fruit, nuts and condiments in special bins deep inside the house, but displayed the heads and horns of aurochs near the entrance. While the latter had a religious overtone they also remembered feasts, episodes of sharing that mitigated the provocations of a full larder.
