Who is the Modern Gadfly?

I believe the most common gadfly would be teenagers. We are constantly looking for ways to do things different and "go against the grain." This embodies the definition of a gadfly because, if you tell a teenager not to do something, more times than not, they're going to do it. Teenagers are notoriously known for getting into trouble for doing something that they weren't supposed to be doing. A reason, in my opinion, would be that we always think that we are right. Teenagers don't care who tells them what, they will most definitely challenge it to see whether or not they really want to do it that way. Actually, in a way, all people have been gadflies sometimes. Nobody who is self-respecting would just go along with everything they see and hear (unless of course you're Candide). LOL
