one time i went to a bar with my friend, there was these two girls there, literally the entire night all they did was take photos of each other. they went to the dance floor for 30 seconds to take a photo pretending to dance then went back to their booth taking more photos pretending to drink cocktails it was peak mental illness, they spent the whole night out pretending to go out but actually didn't drink or dance or talk to anyone, just staged photos and went home
