I'm sure a great many BCG members are old enough to remember the days when all (or almost all) films were made in black and white.
One of the strangest things about those old films is that, when a woman suddenly encountered a dead body, she would almost invariably scream. Did women in real life actually do that?
Another of the strangest things about those old films is that people would fall in love (either unilaterally or with each other) before they'd been out on a first date or even had a conversation with the object of their affections.
I remember one old film in which a man (John Mills?) used to visit a shop on a frequent basis in order to buy a newspaper or cigarettes or something similar. As a result of his very brief and businesslike interactions with the shop assistant behind the counter, he and she fell in love with each other and, one day, he just blurted out "I love you" and she replied, "I love you too". Did that ever happen in real life?
