So basically, my gf has a pretty big family with a lot of cousins etc. She wants to go to a “party/club” and I heard from one of her cousins (a very good friend of me) that he might go as well. Now that wouldn’t be a problem, the problem is that they both probably will end up drunk and if they see each other drunk they’re gonna tell their parents. So I wanted to warn her so she would be warned but then I thought, what if she doesn’t go? Then I would have “snitched” her cousins who are very good friends of me. So, WIBTA if I warn her?
