In the body by Stephen King why does Gordie tell the story about his brother Danny?

Answer 1

Denny, not Danny. I think it was for 2 reasons:

1: To explain why his parents were so distant and cold

2: To emphasize that his friends were essentially the only family he had, and that he had known the love of brotherhood and valued his friends (Chris especially) as he would a brother.

Answer 2

Gordie tells the story about his brother Danny as a way to share his own feelings of loss, guilt, and longing for connection with his friends. By recounting his memories of Danny, Gordie is able to process his grief and come to terms with his emotions, allowing him to bond with his friends on a deeper level. Additionally, sharing personal stories helps Gordie and his friends navigate through the challenges they face together, ultimately bringing them closer as a group.
