I missed something.
I saw this on Friday night and I stepped out to get a refill of my soda.
It was the scene in a motel room. I forgot what they started talking about. But it was sweet and it was nice. Then I came back and Joyce (Streisand) is yelling at Andy about something. I assumed he admitted he went to UCLA to get away from her, which he reveals later that he went specifically for their science program.
She was saying stuff like she was hurt that he tried to get away from her, and then went to the scene where she was drinking at the bar being assaulted by the trucker.
"What happened to my sweet girl?"
"SHE'S GONE!"
