Hats, almost completely removed from formal settings and now only in informal settings.
People have a much more rigid and accurate sense of time. You don’t meet for lunch, you meet at 12pm on the dot. People don’t wait for someone for half an hour, they wait like 5 minutes or so.
People talk much more openly about problems and their views. When I was young people didn’t really talk about religion, politics, medical issues, and so on in public. Now people will tell you they are on an antidepressant or LGBT+ and be open about things.
Hold their hairs that normally fall out in place until they are on camera then shed all at once.
Make their eyes water whenever they are on camera by pushing just a little too much air at them.
Wardrobe malfunctions are an option, but I think making them fumble everything would be better, so they try to hold a pen and it slips out of their hand etc.
Make the camera drift upwards so they look shorter.
