When you live with other people, it’s handy if they know where you are. Not that you have to report to them at all times. And I must be honest, this idea would look perfect in any apartment, not just in your dorm room. For example, it would look perfect in a kid’s room. Parents always want to know where their children are. Yes, I know you can call them on their cell phone, but sometimes you just don’t want to interrupt them that way.
