What is the main conflict in The Hotel New Hampshire by John Irving?

As the story opens, John Berry and his siblings are listening yet again to the story of a bear called "State O' Maine," the bear's owner who is a Jewish man known simply as "Freud," and how the bear came to be part of the lives of their parents on the summer they fell in love. As the story unfolds, the children object to specific statements, insisting that the story be told correctly. John's siblings include his older brother and sister, Frank and Franny, and younger siblings Lilly and Egg. The story is so familiar that all five of the children will sit still and listen, often adding pieces of information.
