 one big thing you need to be looking for more than anything else is change. If you're just now learning body language, you're getting started in it, I would say you need to be a change detection expert before you even learn any of this other stuff. Here's how they look normally and something is different. Get really good at that, then get good at other stuff. And this Christmas, whether you're at a Christmas party or you're watching somebody open a gift, get really good at looking at changes in blink rate. Somebody opens a present and you see a giant spike in blink rate, you're like, you know what, I kept the return receipt for that. Just in case. And when you're at the little family or corporate Christmas parties, you start seeing a conversation with somebody, look who's blink rate is faster than the other persons and then interrupt briefly to talk to the person with the higher blink rate and they'll be more relieved that you briefly interrupted the conversation.
