Sidewalk semiotics

My five year old next door neighbor's babysitter is standing in front of our building facing the street. Two men face her. One kisses her on the mouth quite Romeo like, he stands back and then moves in again, she raises her head again and he completes a second similar delivery. He then looks over at the man to his right, waits a beat and then lightly smacks him on the back of his head. Tapped head guy kisses the babysitter on the cheek, the three of them get in a car and drive off.
