Grace Kelly plays Lisa Carol Fremont (perhaps the archetypical Hitchcock blond) in Rear Window.
There is an unaffected world-weariness in her dialogue as she and Jimmy Stewart’s L.B. ‘Jeff’ Jeffries observe firstly the lonely woman they have nicknamed ‘Miss Lonelyhearts’, and then a young aspiring dancer they have nick-named ‘Miss Torso’ entertain some gentlemen callers.
Kelly was a good actor, but perhaps these lines were somewhat familiar to her experience as well.

Jeff: ‘Miss Lonelyhearts.’ Well, at least that’s something you’ll never have to worry about.
Lisa: Oh? You can see my apartment from here, all the way up on 63rd Street?
Jeff: No, not exactly…but we have a little apartment here that’s probably about as popular as yours. You remember of course ‘Miss Torso,’ the ballet dancer. She’s like a Queen Bee with her pick of the drones.
Lisa: I’d say she’s doing a woman’s hardest job – Juggling Wolves.
Jeff: [watching ‘Miss Torso’ briefly kiss one of the men on the balcony] She picked the most prosperous-looking one.
Lisa: She’s not in love with him or any of them.
Jeff: How can you tell that from here?
Lisa: You said it resembled my apartment, didn’t you?
