He says
Because you have changed the world for me. It’s as though I had been groping about in the dark, and then–sunrise! And there’s a queer feeling here.
(He puts his hand on his heart.)
To tell the honest truth, there’s a still queerer feeling in the pit of my stomach.
It’s a gone feeling, if you must know.
And my knees are weak.
I know now why men used to fall on their knees when they told a girl they loved her; it was because they couldn’t stand up. And there’s a feeling in my feet as though I were walking on air. And–And I could die for you and be glad of the chance.
It’s perfectly absurd, but it’s absolutely true.
I’ve never spoken to you before, and heaven knows I may never get a chance to speak to you again, but I’d never forgive myself if I didn’t say this to you now.
I love you! love you! love you!
Now tell me I’m a fool. Tell me to go. Anything–I’ve said my say. . . . Why don’t you speak?
