What is the Releasing Room and the releasing ceremony?

People deemed no longer desirable, like the elderly, are released. "Released" is really just a euphemism for being killed. Larissa explains that a celebration of release entails the telling of a person's life, a toast, the chanting of the anthem, the person's good-bye speech, and a few more speeches. Afterward, the excited person bows and walks into the Releasing Room. No one but the committee knows what occurs in the Releasing Room, and children are not allowed to attend. The people who are being released think they are going to enter some kind of paradise. In reality they are killed.
