Lost phone lesson

Jr High Drama!! Justin lost his cell phone two weeks ago, as this has happened before with him and we have found it in some obscure place (under the bed, in some old jeans etc.) Andy and I were not too excited, we figured it would turn up at some point. Well... we totally got schooled this week. Justin did loose his phone, he lost it at school. Some kid found it and decided to own it for a few weeks. We initially were monitoring the minutes, and as there were no big changes we figured... we'll find it.
To our surprise the minutes never changed because... they weren't using it for phone calls, they were using it to text. They texted over 3000 messages @ ten cents a pop. You can imagine the shock when our bill was more than quadrupuled (Over $500). We reported the phone stolen and called a few of the numbers to try to catch the little perp. As you can imagine his friends gave him up rather quickly once I mentioned that the police were involved. (We live in a small town and you can still scare kids with a police threat). So this boy is now in major trouble, and hopefully will learn his lesson.
What was really disturbing, was that the kids were texting starting @ 3 AM and every 15 minutes after that, non stop until 9PM. All thru school, breakfast, lunch, dinner and potty breaks. All the while parents and teachers were clueless.
Thankfully we are getting reimbursed by him and his parents for charges and a phone replacement.
Justin seems to be handling it o.k. We are a bit concerned over retaliation, which the principle of the school assured us will not be tolerated, but you never know. Keep him in your prayers as these next few days maybe rocky.
