the Icebox Syndrome, because you think of it after you've gone home and are looking in the fridge.
Most of us have seen Meet Me in St. Louis (1944) lots of times and believe we know every part of it intimately, even its quirks. Well, recently this icebox moment occurred to me. When Esther apologizes for slapping John around, he accepts her apology but - and here's the kicker - he never asks her why she hits him in the first place.
The audience knows why since we're there when little sister Tootie claims the boy next door hit her. Esther runs over to 5133 Kensington Avenue and gives the guy what for. After discovering that her sociopathic sister has lied, she asks John's forgiveness (without explanation) and he gives it. They then chat about nothing and he plants a great big smooch on the woman who just assaulted him, asking her, "if you're not busy tomorrow night, could you beat me up again?"
What is going on in this character's head? How does he rationalize her behavior? She's clearly angry, but does he consider the slaps gestures of romantic interest? If smacking and such turns him on, he'll fit right in with this crazy family.
