Teenage girl here - ready to answer any questions about my generation if required - I'm not a drinker - heavily against underage drinking - but feel free to fire away any questions about it - I see it all the time.
From my experience - just dont glorify it or in any way show that being drunk is something that impresses people. Dont share funny stories about the time so ans so got drunk because she might throw them back at you.
Just act (or be) disappointed with her. If you lay down too many rules or go off at her she'ss just want to do it more or use it as escapism.
If that doesn't help you - probe me further. I represent my generation as ambassador.
