I’ve never seen myself in a film (not a big screen film), but a video, home movie or anything more flickering than a dropped photograph. And even photographs are rare.
Until we see ourselves moving, walking and talking, we never really know how we come across to other people. It’s why there’s a big industry in teaching professionals how to present themselves. Unless you have video evidence to the contrary we have no idea just how big an arsehole we might appear to others.
