text: These are all the reasons why the facial action coding system is vauable for students in a classroom. It can show them the advance in technology and help them with things that express on their face. This is why this product will be vauable.   Dear principle, I don't think all of the students should have to do community service. I don't think all kids should do community service because I find that as a punishment for doing something bad. I don't believe all students should have to do community service because prisoners of jail have to sometimes do that. Or other naughty teenagers have to do that. So I don't believe good teenagers have to pick up trash or have to do any other subjects like that. Plus if a student signed up for football every day after school from 3-5 pm and community service is from 3-4 pm. What do the parents who paid all that money do know? The football organization doesn't give it back. The parents are out of that money and the child inst playing football which the money went to in the first place. So really it would be affecting the parents and the parents wouldn't be happy with you.
