 It's easy to think of tough comebacks when you're alone. But when you're standing face to face with an opponent, you wouldn't dare say a word. Hi, I'm Mark Gregston with Parenting Today's Teens. Many teens who are not typically bullies are using the internet as an outlet for their mean-spirited words. Because online identities are anonymous, kids are discovering what I like to call digital courage and using Facebook, Twitter, and other social media sites to say things they wouldn't otherwise say in person.
