What do you think about refusing to get my brother some e-juice when he asks?
Why are you going to do that?
I need to start saving money.
It is wrong to buy e juice for someone underage. You can go to jail if you get caught.
I live alone so what do you care.
It doesn't matter if you live alone you should care about what happens to you. You should not break the law even for family. You should go ahead and refuse to do something if you know it will cause them harm.
