You and your SO/close friend are going out together for the night. Your SO/friend drives their car and you ride along. Sometime during the night, they get high/drunk and can no longer drive their car. You end up driving their car back to your place, and you have the following options. What do you choose?
a not-so hypothetical question
Make them drive their ass home, who cares if they're under the influence.
If they ask to stay, begrudgingly let them. If not, let them go.
Don't take no for an answer, they are intoxicated and will not be driving, no matter how mad I am.
Other option that I will explain in the comments.
