Also good to know. As Tony tells me, the functionality for me to know where their phones are must just be ON the phones, but I really don't want to be checking that all the time. I know it's an unsafe world, but honestly, 1. they're probably the least safe (from a school-shooting standpoint) when I know where they are, in school, and 2. I also know sometimes you can do all the preparing in the world and still sometimes just have bad luck/not have your phone with you.
MMMMmmmmm rural southwest England, that sounds nice right about now. :)
