He's a grown ass man. U shouldn't gave to be playing babysitter. If I were in your shoes I'd tell him exactly that and that you need to study so he needs to make his own decisions and hopefully he will make the right one. But really, you can't be responsible for his actions

You should brin the books with you and while he's drinking study

Option 3: Sit him down have a heart to heart talk with the old man and tell him that you care too much about him to watch him hurt himself. Offer to help him find help. This sounds like his dad has a drinking problem and he needs to be confronted about it.

Tell him to **** off bro

maybe your dad should take responsibility for himself since youre clearly trying to do something with your life and he should be an adult

OR you could deny him access to your car and tell him to find his own damn way to get around

Never need to study for exams if you read the book Before classes start back up and then pay attention about 50% of classes and you'll ace it every time without fail.

If I were you, I'd let him drink and drive. It shouldn't be, and isn't your responsibility if he has a crash or gets fined.
