In "Where Rainbows End" by Cecelia Ahern, a character named UnsureOne reflects on the longevity and evolution of a friendship. They consider the deep bond formed since childhood, noting that despite both individuals being thirty-two and having experienced marriages, their relationship hasn't progressed romantically.

This contemplation leads to the realization that after so many years, if romantic feelings haven't developed between them, it's likely that they never will. The sentiment captures the complexity of long-term friendships and the challenges of transitioning them into romantic relationships.
