text: In conclusion, people shouldn't use cellphones while operating a vehicle. IF they do it can cause life changing accidents and other serious problems in life. Also, it can hurt some people financially causing them to pay for these uneventful occurrences. Some things people can do to prevent is to turn their phone off or put it on "Do Not Disturb" mode to prevent any accidents. They can also deal with that they have to do on the phone before starting the car and driving. One more solution is that they can have the passenger relay a message for you using your phone, so you won't be distracted or tempted to pick up the phone.      Is it a really a good thing to read someone emotions? well it is, if you see someone who's mad, sad, fearful, you can help them to calm down, to feel better, or to feel less scare. emotions really lets someone to show everyone how they feel. But using the Facial Action Coding System (or FACS) on classroom full with students could be a good/bad idea. One teachers can see if students are confuse or lost, two they see if there's something wrong with one of the students, three some students don't want their's teachers to be in their's problems.
