My answer

I don't think the society in Giver has only one receiver. If only one person have memory and feel pain, there is no method when he makes wrong decisions or he suddenly get big problem like disease or dead. And I think the receiver needs another person who has some rights. Because, there is possibility the one missunderstood about memory. So, the one needs another one who can dicuss with him.

Memory is bulit on many experience. Perhaps, there is hapiness, but there is also sadness in experience. So, memory generates pain that is caused from sadness experience. And, wisdom is built on memory. If we don't have any memory, we will not have wisdom. Because that means that we have not experienced. How do we decide correctly without any experience?
