Because people on the autistic spectrum tend to lack the ability to ‘mirror’ other people’s body language, autistics often have trouble making the right facial expressions on cue. If you have this problem, it may help to check your facial expressions in a mirror, but using a mirror discreetly can be a challenge. I get around the problem by using a mirror watch. It’s basically a mirror on your wrist (the time only shows if you press a button). That way, you can check your ‘look’ while pretending to read the time. If you’re buying one, make sure to check the size, because they tend to be a little larger than the average watch.
