I feel like some people need to understand that this event seems to be more like a choreographed program, almost like a play, not a typical school dance where the school just provides a venue and music for kids to dance and socialize in. It appears that they practice the dances at school before the event, and there are limitations such as only being able to dance with a person once. So part of participating in the event is interacting with other people, even if they wouldn't be someone you would necessarily choose. Maybe the school needs to do a better job explaining this and explaining the conditions, but I can kind of see what the school's intentions are here.
