His friends are unable to find him and they are all trying to leave
Hey guys, this is getting pretty boring, let's leave
Corey's friends assumed he left already. So they decided to leave as well
Corey drunk, wants to leave the party but he can't find any of his friends, so he decides that driving himself is the best option
*Corey Drunk*Hey, my friends left but I think I'm just going to drive home myself. I'll be fine.
Another girl at the party overhears him, and insists that he find another way home. She didn't drink that night so she offers him a ride home or to call an uber for him, explaining that it's very dangerous for him to get behind a wheel right now.
Excuse me, but you definitely shouldn't do that. It isn't safe for you or other people on the road. I haven't drank so if you want I can give you a ride home or call an uber.
Corey then realizes that he is very drunk, and that driving home is not the best option for him. So he listens to the girl and let's her drive him home.
Yeah, you're right. If it's alright can you give me a ride home?
