Agree and get dressed
From Create Your Own Story
You get dressed, clearly looking a bit disappointed.
Laughing she says, "Look Will, you're a nice guy and I definitely want to do this again. Soon. Just not tonight, OK? Mia, my babysitter will be here early and I'm already worried about what Angie will tell her."
Despite your blue balls, you know you're going to have to respect the lady's wishes.
Once dressed you exchange phone numbers, say goodnight, and leave.
