In John Irving's "The Hotel New Hampshire," the theme of familial relationships is explored through the lens of shared experiences, including sorrow, love, and ultimately doom. The idea is presented that doom is a prevalent and inevitable element in family life, suggesting that it is an intrinsic part of human experience. This notion highlights how families often face challenges and hardships, which contribute to a cycle of emotional highs and lows.

The quote emphasizes that while love and sorrow are significant emotions within families, the concept of doom is also commonly present. It suggests that these feelings are fluid and can coexist, floating in and out of family dynamics. This perspective invites readers to reflect on how these emotions shape relationships and the overall journey of life within a family structure.
