Rate the following essay on its writing, argument, and language skills:
In my opinion i think that it is useless. I mean, why would someone want to know how you feel in class? I know your friends will probably want to know but they can just ask instead of pulling out their computer and scanning your face and doing all this research. It's an interesting thing but at the same time it's kinda useless. In paragraph 8 it states that an expert knows when your facial expression is lying.

It states that " these muscle clues are sometimes used to spot when a "smiling" politician or celebrity isn't being truthful." To be honest, i couldn't care less if a celebrity or anyone else is fake smiling at me. How will this device benefit you is the real question. In paragraph 5 it states that " most of us would have trouble actually describing each facial trait that conveys happy, worried, etc. " but in paragraph 7 it explains to you if you look into a mirror and do it step by step how to look happy, it will make you look happy. It even states " does your expression in the mirror suggest an emotion? Can your lab partner recognize which one? In fact, these are the instruction for a face that looks happy."

If they invented a whole app to tell them how you're feeling and didn't know how to explain how someone is feeling, they wouldn't have explained perfectly a person who is happy, even step by step. They device could be helpful just like the lie detecting test the polices use. But if you ask me, it's useless. In the 6th paragraph it states that The Mona Lisa is intended to bring a smile to your face, if you smile around anyone, they will smile, smiling is contagious then you'll know how they're feeling instead of wasting a lot of money on an expensive device.

In conclusion, if you want to wate your money on something useless, you can. To me, it would be smarter to invent something more useful instead of worrying about how someone else feels or how your entire class feels but at the same time the people who invented that are getting paid and that's all that matters.
