Does sex make it impossible for men and women to be true friends?
Harry:I've been doing a lot of thinking, and the thing is, I love you.
Harry: I love you.
Sally: How do you expect me to respond to this?
Harry: How about, 'You love me too'?
Sally: How about, 'I'm leaving.'
Harry: Doesn't what I've said mean anything to you?
Sally: I'm sorry Harry, I know it's New Year's Eve, I know you're feeling lonely, but you can't just show up here, tell me you love me and expect everything to be all right. It doesn't work that way.
Harry: Well how does it work?
Sally: I don't know, but not this way.
Harry: Well how about this way. I love that you get cold when it's 71 degrees out, I love that it takes you an hour and a half to order a sandwich, I love when you get a little crinkle above your nose when you're looking at me like I'm nuts, I love that after I've spent the day with you, I can still smell your perfume on my clothes. And I love that you are the last person I want to talk to before I go to sleep at night. And it's not because I'm lonely, and it's not because it's New Year's Eve. I came here tonight because when you realize you want to spend the rest of your life with somebody, you want the rest of your life to begin as soon as possible.
Sally: That's just like you, Harry, you make it impossible to hate you; and I really hate you, I really hate you
