As far as not knowing what is going on with them because of facebook texting and etc, shame on you...that is an excellent resource for parents to be able to not only see what's happening with your child, but also your childs friends. You would be amazed at what you can find out about people. Businesses use it when hiring, colleges use it when accepting students, why not parents? Mine know that their phones and their Internet usage will be monitored or else they won't have it for long!
Call me paranoid, call me nosey?! I don't care. I wish more parents would do the same!
