The Receiver's job is to receive memories, yes. Also, to transition into the role of The Giver. Once the Giver has given the memories to the receiver, the receiver will become the Giver. Then it will be his job to hold onto those memories so that the rest of the community doesn't have to know about them. Then, periodically, the council might ask the Giver for advice on a particular situation, and he will draw upon his memories to help them find a solution to their problems or an answer for their questions. The life of the Giver is mostly quiet and lonely, since no one else in the whole community understands what he knows, or can see the world as he can. Even just the simple ability to see color separates him from the rest of the world that can't see them. So, mostly, he stays in his quarters and reads books, and waits for someone to need his services. After that, he will just wait until it is time to train a new Receiver to take his place.
