My DD is at an all-girls school as well and their dances are alive and well! There is some grinding, but it’s not the majority of girls and most of them think that’s pretty gross. They mostly like going and dancing with their girlfriends and meeting some of the guys from the visiting schools.
@Golfgr8 I love your comment! My DD goes to a month long camp in the mountains and like you said, there are no electronics, no phone, no social media and those teenagers REALLY look forward to the square dance they have! ?
