It's kind to offer your friends a ride home.
Clay and his friend Jack are at a party where Jack drinks too much and gets drunk, but Clay remains sober.
Clay wants to leave the party.
Clay asks Jack if he needs a ride home as he's obviously too drunk to drive.
Clay tells Jack and the others at the party he will be leaving and to have a great night.
Jack accepts the ride and picks up his car the next day when he's sober.
Jack ends up with no one to take him home so drives his own car drunk and gets into an accident.
