Is your child having a tough time listening to you when it comes to rules for using the internet?  Do you constantly catch them talking to people they shouldn’t, and even sometimes giving out contact information?  If this sounds like your child, there is no reason to get upset.  The fact of the matter is that if you start to yell at them, they are just going to revolt against you.  You have to get on their side first, and then you can start to correct the problem.
