So what is this all about, the GPS, the FB, rude text messages, the lost Ipod, etc? This girl's mom thinks your daughter A) stole the Ipod B) hacked her daughter's FB and changed her settings C) with great technical skill managed to send anonymous mean text messages to all of her daughter's friends? And she bought into the 12-year-old's drama and went around tracking cell phone messages?
Now the Mom is asserting that your daughter is sending mean text messages about her daughter to all their friends. Text messages are not anonymous messages. When you send a text your phone number appears on it. You know who you are getting them from when they arrive. What does she think, that your daughter went out and bought a pay-per-use cell phone to bash her daughter? For what reason?
This mom must think your daughter is bound for silicon valley, while she's traipsing around GPS tracking text messages and cell phones. Frankly, the mom is a little too involved in the whole issue.
I have a real good solution to the problem. Get rid of the expensive Ipod, the cell phone and FaceBook account for a 12-year-old.
They don't need those kinds of things, they aren't old enough to have acquired the judgement to handle them, and this just demonstrates it. Kids this age are vastly impressionable, expecially by their peers and current trends. It's very difficult to keep them focused on their studies. These kind of electronic devices cause further distraction and many problems. The music they are exposed to may be sexually explicit, they can get into trouble with sexting and bullying situations with a cell phone and FB. They should be involved with healthy activities such as sports, dance or other physical activity type classes, and working on academic skills/getting ready for a vocation or college. If they have extra time, volunteering in organizations that help others and helping around the house, are activities that help them mature into competant adults.
Please make sure that your daughter doesn't have access to any of these devices and a lot of your current problem will cease to exist.
I suggest that you relay what we say to this mom and let her know that if she continues her vendetta against your child that you will obtain a restraining order.
