If you're on the wrong side, you might miss it. So you got to be super careful that if you see it, you always want to confirm it. So, for example, with some of our models, if they made a smirk on the left hand side, but our camera was on the right hand side, we missed it. We missed their contempt. And so it's very, very important, if you think you see contempt, you are confirming it. Here's an example. She showed contempt on her right hand side, but our camera was on her left, so we missed it. Whereas here's an example of someone who contempted on the correct side of our camera. So, so we caught it. But you'll notice that from the side, it could be happiness. It's very, very hard to tell the difference if you're from the side, between happiness and contempt.
