Can I take my friends keys after she had to many shots?
Are you planning on taking the keys away now?
Yes, she can't be trusted to drive home.
Its very responsible of you to take your friends keys away so they dont drive drunk. Drunk driving is one of the worst mistakes someone can make in their life, and you preventing it was a very mature thing to do.
I kind of want to drink now though too.
Wouldn't you want the both of you to be safe going home? How about waiting to drink until you go home?
