"Cooking gave us not just the meal but also the occasion: the practice of eating together at an appointed time and place. This was something new under the sun, for the forager of raw food would have likely fed himself on the go and alone, like all the other animals. (Or, come to think of it, like the industrial eaters we've more recently become, grazing at gas stations and eating by ourselves whenever and wherever.) But sitting down to common meals, making eye contact, sharing food, and exercising self-restraint all served to civilize us."
