You shouldn't let people drive buzzed.
Henry and Peter are leaving the bar after a night of drinking and Peter is walking to his car and says goodbye to Henry.
Henry wants to respond to Peter's goodbye.
Henry tells Peter that he's not letting him drive since he drank and that there is no goodbye since they're both taking the bus together.
Henry tells Peter to have a great night and continues to walk towards the bus stop.
Peter snaps out of it and realizes he was about to drive drunk and thanks Henry for saving him from trouble.
Peter gets in the car and drives a short while before slamming into a light pole and hurting himself.
