Finding paragraph #2

I'm writing about having cell phones off when you are in schools. The reason I'm writing about mobile devices because many teacher doesn't want the students to have their phones out while in class. When having the phones out the teachers wants to know why they students have their phones out in class. What teachers don't realize that having a cell phone is very important. Something that I think that is important is that it could be a problem with the child parents and they don't have no other kind of way. Another reason is if they stay after school in they can't get to a phone they could have their cell phones to call their parents to come pick them up.
