Yes, its lying!

Those of you who really wants to learn or train for facial expression, are better to purchase learning tool at Dr. Paul Ekman web page. Or just read his book!
This app wont be a learning tool because it has fake facial expressions too much as someone evaluated so.
Even I tried to find a key for the word "surprised," I could not find it. I could not believe it.
But for joke, it is good.
