HIM: "Oh come on! Who's gonna see us at this hour?"
HER: "No, please. Can you imagine if we get caught?"
HIM: "Oh come on, there's nobody around, they're all sleeping!"
HER: "No way. It's just too risky!"
HIM: "Oh please, please, I love you so much?!?"
HER: "No, no, and no. I love you too, but I just can't!"
HIM: "Oh, yes you can. Please?"
HER: "No, no. I just can't"
HIM: "I'm begging you..."
