Well I don't drink or party anymore. But when I was younger I'd go to raves, metal shows/gigs, Ska gigs, punk gigs, rockabilly gigs, hip hop parties.

I'd just get really drunk and talkative and friendly.

If I were at a house party now? I'd just chill on the couch, wouldn't drink and just be on my phone. I'd talk to people but not excessively unless they are persistent.

Druggie full of strangers? I would be very alert, not on my phone at all, and watching my back for how ever long I needed to be there because shit is gunna go down. And I don't trust them.

But I'd make sure I mingled and acted like in happy to be there so I don't become a target for anything.

Dinner party

I'd have a glass or wine or two and talk to everyone
