In a small park in D.C. late at night, a couple walk along the area, Melanie is singing to her baby which is in a pram that her male companion is pushing.
Neil wonders if they can stop walking now.
Melanie tells him to hush and that if Neil stops moving, then their baby son will wake up.
Neil complains that it's almost 2am and that their son's gonna be hungry again in an hour.
As they walk along the area, Neil states that he read about a kid that couldn't sleep until he was in a moving car and that the kid's parents drove 3000 miles in a month.

"Give me ten", Neil suggests.
"Greedy", Melanie says.
