I actually think this was pretty responsible. Rather than banning it outright, which would result in kids wanting to rebel even more, she offers it in her home where she can control the amount people drink. Good on ya, Mrs George. You’re a cool mom.
She also offered her daughter a condom when she was hooking up with a guy instead of freaking out and kicking the guy out of the house.
It’s kinda funny how she is simultaneously an out-there parent, yet not a bad one. She might actually understand that her daughter is a anger-ridden teenager who can’t be easily controlled and restricted, so instead of telling her what she can’t do, she tries to guide her to a safer decision. I’m not saying I’m 100% cool with how she executes it, but hey, not a bad parent when you think about it.
