How to Deal With Sisters

Don't say anything to him until you witness something yourself. Your sister behaves recklessly and you don't know the full story or if it's even true. Be there to protect her and make sure she's safe. That's the most a brother can do. Protect and Defend when something goes down.

At least I get to be drunk, frequently for free. It's pretty much mandatory with the games her social circle plays. God, "Never Have I Ever" was not fun, though. She drank too many times.
