STRANGER CRUSH--knowing when to fold 'em:
"One day back in 1896 I was crossing over to Jersey on the ferry. And as we pulled out there was another ferry pulling in. And on it there was a girl waiting to get off. A white dress she had on, and she was carrying a white parasol. I only saw her for one second. She didn't see me at all. But I'll bet a month hasn't gone by since that I haven't thought of that girl."
From CITIZEN KANE, screenplay by Herman J. Mankiewicz and Orson Welles.
