A bit of Instruction on what to look for would be great...

I love the TV show, so I had to grab the app when I saw it. Currently, it shows you a person that makes a facial expression and you decide between certain emotions, but it never tells you what you should be looking for. The only thing that is missing is an instructional part that explains why a facial expression is considered joyful instead of just amused or why someone is crazy and not just angry.
