I like the proposal scene, where she gives the Terms and Conditions of her acceptance.
Young Denis Thatcher: Margaret, will you marry me?I also like when they go to the opera, and he gives her a little pink fake mouse.
Young Denis Thatcher: [pause -Margaret stares at him] Well?
Young Margaret Thatcher: [pause -Margaret is still staring, Dennis kisses her hand] Yes. Yes!
Young Denis Thatcher: [Margaret starts to cry from happiness, Dennis leans in for a kiss, but she suddenly pulls back] What?
Young Margaret Thatcher: I love you so much but, I will never be one of those women, Dennis. Who stays silent and pretty on the arm of her husband. Or remote and alone in the kitchen -doing the washing up, for that matter.
Young Denis Thatcher: [Interrupts] I'm going to help with that...
Young Margaret Thatcher: No. One's life must matter, Dennis. Beyond all the cooking and the cleaning and the children. One's life must mean more than that. I cannot die washing up a teacup! I mean it, Dennis. Say you understand.
Young Denis Thatcher: That's why I want to marry you, my dear.
Later, when she's running for office, the members of parliament who served as her campaign managers are very encouraging!
