The novel takes a moment away from Carol Kennicott to tell us about the inner life of Vida Sherwin. It turns out that Vida had a bit of a thing going with Will Kennicott that never panned out, but Vida was still a little crushed when she found out Will had married Carol. Carol never knew that Vida would have some secret reason to dislike her.
It doesn't make Vida's life any easier when she realizes that Carol thinks she's above everyone in Gopher Prairie. Still, she tries her best to like Carol and to be like a big sister to her.
Eventually, Vida starts hanging out with Raymie Wutherspoon, and they strike up a deep friendship. Then, when both of them are nearing the age of forty, they get married.
It's clear to everyone in the town that Vida and Raymie are much happier once they're married.
