...I've never proposed before

Stanley:

[sees Sophie reading on a swing]
Taken to reading the great books? Sophie:
Yes. [Stanley says nothing] Sophie:
Well, you once said not to despair. There's hope for my brain. Stanley:
Perhaps I was a bit caustic... But you will admit you were guilty of some rather sleazy doings. Sophie:
Yes, well, those days are over. I no longer have to worry about where to sleep and how to eat. Stanley:
I take it Brice Catledge has made a serious marriage proposal? Sophie:
Yes. A very tempting one. Wouldn't you agree? Stanley:
Yes, I suppose so. But I'm here to make you a More tempting one. Sophie:
More tempting than this? [shows ring with big rock] Stanley:
I came to say, that for some inexplicable reason that defines common sense and human understanding, that I have of late experienced some small... quite small, but discernible, inner stirrings regarding your smile. Sophie:
How magnanimous of you. Stanley:
Yes, I thought you'd think so. [Sophie rolls her eyes] Stanley:
And possessing a soul which is large and capable of complexity, as all great minds are, I have decided to forgive you and take you under my wing. Sophie:
Your wing? Stanley:
It's a saying. Obviously, I don't have wings. I only mean that, incredible as it sounds, and this is no small gesture, given the time wasted and the public embarrassment you've caused me, that I'm willing to take you back. Sophie:
Take me back where? Stanley:
Under the moon in the observatory. Sophie:
...I regretted what I was doing; I was too inept to change course, and I apologise. Really. And I accept your forgiveness. I understand that it's very generous of you, and I have to be going. Stanley:
Going? I haven't said what I came for. Sophie:
Well, then just say it, and go, because I have a dinner to go to with my fiancé. Stanley:
...I'm here to say... that in spite of everything, I am willing to consider marrying you. Sophie:
What? Stanley:
Naturally, you can't believe your good fortune, I appreciate that. Sophie:
Stanley, brilliant as you are with a deck of cards, you are *terrible* at proposing. Stanley:
...I've never proposed before
