We were watching Neil Simon's The Odd Couple in creative writing class today (playwrighting time) and there is a scene, toward the end of the film, in which the "Pidgeon sisters" come into Oscar's apartment. The guys, who are sitting playing poker, all stand up when the ladies enter.
I stopped the movie.
In an effort to point to the quick decline in manners, I mentioned that the film was made in 1969, a year after I was born, and that, apparently, in some social spheres, men were still standing up when a ladies entered a room.
One of the girls, honestly and openly, raised her hand and asked, "Why did they do that?"
[Sigh.]
