Lucky: There are no other girls besides Maisie. Ginny: James! Do you really feel that way? Lucky: Can we please talk about something else? Ginny: No, no, no, absolutely not. Come here. Do you really feel that way? Lucky: I can't help it. I mean, every time I look at her, I get this... this hollow feeling in my chest, and it's like... it's like someone literally took a shovel and dug a hole in me. It's the worst feeling I've ever had in my life, and I didn't—I didn't know anyone could actually ever feel this bad. Ginny: I know. Everyone knows eventually. I promise you, it does go away. Lucky: I don't want it to.
