I think that parents should check their child's emails and text messages. For those of you who think that this is too much work, parenting is hard work. I know that we should all trust our kids, but even the best kids will test the boundaries. Children need guidance from their parents until they become adults. Even the best kids will make mistakes in life but we as parents have to help them through the times when they make mistakes.
In the age of electronics, a simple comment or snapshot can go viral worldwide in a matter of seconds. There can be major consequences as a result of a simple email or text message. The one thing that needs to be emphasized with children is that whenever you put something in an email or text, you no longer have any control over what happens to that information. Parents also need to address the seriousness of sexting with their children. If your child forwards an inappropriate photo, he/she can be considered just as guilty as the person who took the photo.
This new age of electronics allows people to become bullies who wouldn't otherwise have the guts to be mean. There have been several stories of teenagers committing suicide because of cyber bullying. If parents would periodically check their child's emails and text messages, most children would be less likely to behave inappropriately. I know that there is such a thing as "Delete". Young people tend to have short term memory, so odds are that if you don't check emails/texts everyday, they will forget to delete the inappropriate items.
Unfortunately, emails and text messages as well as internet searches are all new things that we have to deal with as parents, that our parents did not encounter. I think I liked my simple life as a kid. Seven or eight television channels, playing hide-n-go-seek, jumping rope and playing sports with your neighborhood friends(not on a traveling team).
