Flowers take place in a regular world where Myop is in a sharecropper family and is innocent.
Myop is enjoying a summer when she starts to go am the area behind her house. While she heads there, she is picking flowers. While she is collecting flowers, she steps into a skull but is unfazed by the dead person corpse. But then Myop picks up a flower and sees the rotten noose around the roots. She looks around and sees other rotting remains of a noose hanging over a tree branch. When she looks at this she drops in flowers, and the text states “ And then summer was over”. This is the part when Myop realizes that people kill themselves. That realization takes away Myops
innocence.
The difference between both the stories is that The Giver is in a dystopian setting while flowers take place in the real world. While both Jonas and Myop both lose innocence in some way, there are differences. Jonas lived in a world where he knew nothing and had been receiving memories. These memories are completely new things for Jonas, and nobody but he and the Giver knows it. On the other hand, Myop discovered something that she didn’t know but most others did. She saw the corpse of a man who committed a man committed suicide, she knew that people die and get killed, but the fact that people kill themselves was the thing that shocked her. One similar thing was that death itself was the thing that removes Jonas’s and Myop’s innocence. Jonas seeing soldiers die in war and his father kills a twin, while Myop sees the dead man's corpse.
The Giver and The Flowers both have the main characters experience the pain of reality by giving them a situation where they are forced to lose their innocence. People are usually shocked when they are exposed to such thing. Though you need to lack that knowledge first.
