"Hey, let's make a deal. We can date, just so we're not so lonely and want to shoot every couple we see. When we find a person we want to date for real, we can break it off. Does that sound okay? Is it a deal?"
"Deal."
"Let's make a deal"
"What kind of deal?"
"Well, you want to know my name, and I want to have some fun..."
"Ok, so?"
"Spend the rest of the night having an adventure with me, and if you make it to 7am, I'll tell you my name...but here's the catch: we only do the same thing/stay in the same place for 30 minutes before we leave. No more, no less."
"You've got yourself a deal."
