Setting
Abnegation's initiation ceremony is a quiet affair. The initiates, who spend thirty days performing community service before they can become full members, sit side by side on a bench. One of the older members reads the Abnegation manifesto, then all of the older members wash the initiates feet. Then they all share a meal, each person serving food to the person on his left.
