Just watched The Cranes Are Flying for the first time last night (finally). It's a brilliant film about the challenges of enduring love during the reality of war. The father of Veronica, the girl in love, says this about love to his wife when their daughter returns home in the wee hours of the morning:
MOTHER: She's crazy about him!
FATHER: And he about her.
That's what love is, my dear: A harmless mental illness.
A mental illness, perhaps, but certainly NOT harlmess, in my opinion.
