I wrote the following for the meetup booklet - would you say it avoids giving a manipulative impression?

Anything that involves working smoothly together can feel pleasant. It can be an especially welcome change for people who experience a lot of conflict in their lives, or simply don’t often get a chance to cooperate with others. Synchronized behaviors, like singing, dancing or even just walking to the same beat, are a surprisingly easy way to experience the feeling of cooperating with somebody else. It might sound silly, but people often find these activities enjoyable and feel closer to each other afterwards. If people feel self-conscious, many might regardless appreciate playing dancing- or rhythm-based video games such as Dance Dance Revolution, Stepmania, or Rock Band together. If you have the space and equipment, you can try putting several monitors and dance mats side by side, and starting the same song at the same time in each game. Instant easy line dancing. Singing together is also fun, and it’s often enough if one person knows how to sing the song well, as others can just join in. Drinking songs also work for people who feel more at ease when less sober, but make sure that any non-drinkers don't feel excluded.
