Oh, honey, don't you play with the big girls. You'll be in way over your head

Vicky Robinson:

You're a big girl now, Susan. You're old enough to understand that wonderful, delicate mystery that happens sometimes between a man and a woman. Sharon McKendrick:
I know what wonderful, delicate mystery Daddy sees in you. And I can't say I blame him there, either. You're very nicely put together. Vicky Robinson:
Your father underestimates you, I think. Sharon McKendrick:
I'm sure you won't, will you, Vicky? Vicky Robinson:
Susan, dear, you've had him to yourself all this time, and I can understand that suddenly to have another woman around, well, it's a tremendous intrusion. But all my life, it seemed, I've hoped and waited for someone like him: someone gentle and mature, rough-edged, but quick to laugh, someone understanding and wise. All the things that I've come to love and cherish in him. Sharon McKendrick:
Well, that's very refreshing. Vicky Robinson:
Why, dear? Sharon McKendrick:
Most girls just run after Daddy because he's so wealthy. Vicky Robinson:
[angrily]
Are you inferring that I'd marry Your father for his money? Sharon McKendrick:
If the shoe fits, wear it! Vicky Robinson:
Look, pet. I've tried to be friendly, but I'm going to marry Your father, so you get used to the idea! Sharon McKendrick:
You wanna bet? Vicky Robinson:
Oh, honey, don't you play with the big girls. You'll be in way over your head
