Aunt Lottie's 'problem'
The one scene where Aunt Lottie tells Cora that she "doesn't enjoy it the way most women say they do," left me wondering. Playwright William Inge was gay. And that scene could be an attempt by Inge to introduce the possibility that Aunt Lottie was a Lesbian, trapped in a marriage borne out of conventional expectations of women to get married ... that she was a woman who could not acknowledge or possibly understand her orientation predicament. Just as there are gays and Lesbians who choose not to come out of the closet, and certainly back in the 1920s, there may have been gays and Lesbians who didn't even know they were in a closet ... and were completely confused by feelings considered odd, forbidden, and not to be discussed in (ahem) polite company.
Back in 1960 when the film came out, the unspoken implication of homosexuality could make it past censors. And, that may be why Inge chose not to speak of it with more direct language. Just a thought.
P.S. I'm not gay. But my interpretation of that scene comes from an experience I had. When my maternal grandmother passed away, my mother and I were cleaning out her house. She read quite a few books and had them displayed in a bookcase. But in her bedroom closet was a locked metal box. She'd not left a key that we could find so I had to force it open. Inside, I found a few odds and ends ... costume jewelry, unremarkable stuff ... and one paperback novel titled, "The Loveliest of Friends" - a Lesbian novel. The cover art depicting two women and the summary on the back cover left no doubt of that. I started snickering (I loved Granny and knew she was a bit wild). But I thought my mom was going to have a heart attack when she saw it, hehe.
Point is, there were probably a large number of gay men and Lesbian women who grew up in the 1920s (like she did) and tried to "fit in" to the heterosexual world. My grandmother may have been one of them.
