text: A lot of people wonder how this works they don't really know that one easy way to show emotion or to show how you feel is by looking at them and looking at their actions. Once you have already seen them and that they are feeling some kind of way that's when you realize that there is something going on or that their sad or happy or that they are just going through stuff. People know that by the facial expressions on their face. They say that us as humans perform the same impressive "calculation". Some people struggle or have trouble actually describing each facial trait that conveys happy, worried,sad,etc. This would be one easy way students can detect emotions.
