text: Student sometimes go to after school activities or stay after school to meet with their teacher. In this case, if their soccer practice ends early or their meeting is going to take some more time, students will need to contact a parent to tell them to pick them up earlier or later. If, though, phones are not allowed in school then they will not be able to tell their parents. This will lead to the student have to stay at school once practice ended or try and walk home.
