Open endings, in some cases, it leaves the reader really irritated. But open ending also forces the readers to think and guess what will happen in the rest of the story. It will not give the reader an ending but the reader can think of their own. It gives the reader the choice to their ending bast on the information that they got. There is one reason why an author might choose to have an Ambiguous ending, and here’s why.
The reader wants you to think and give the story an ending best on the information that they give, and your background information. He might think that he is not able to get the reader a perfect ending that they want cause everyone likes their own ending. However, they well give you a huge quantity of clues based on the story and the information. So you can find out the ending that you like.
Lastly, In some ways, I feel that an author allowing us to make up our own minds about the ending of their story is almost an honor. So don’t get mad and keep thinking.
