A League Of Their Own, when the slugger girl, who almost didn't get to go because she wasn't "pretty", is saying to her dad that she doesn't want to leave him and he tells her "Nothin's gonna happen for you here. You gotta go where things can happen." Saw that right before I left for college, and cried like a baby. Also the telegram scene of course, and when Geena Davis' husband comes home.
The scenes mentioned in Hope Floats, but also when the little girl runs after her daddy and he drives away, that just tears my heart out. She sounds just like DD when she's heartbroken. The first time I saw that after DD was born I turned to DH and said "I hope you know I'd just shoot you right there and be done with it." (Actually, I said that when he came back because he couldn't stand to watch, so the warning was unnecessary.)
