If I could chose for an assignment choice in the book “The Giver” by Lois Lowry, I would chose to be the Receiver of Memory. I think that memories must be kept to avoid going back to the old painful warlike days of the past. With the memories, the receiver of memories can advise the elders from making bad choices that could doom the peaceful golden age. Only the memories of learning things the hard way can prevent mistake from happening again.
