Don’t send too many messages. Don’t say anything you wouldn’t want screenshotted. If the group chat goes quiet, it might mean there’s a smaller, more exclusive group chat that you’re not a part of. If you want to post on Instagram, send the batch of photos you’re considering and let everyone weigh in on their favorites. Share your location. You might get kicked out but you could also be added back in. And don’t even bother if you have an Android.
