Poetry in a Nutshell

Heroes. These amazing storybook characters that every person, child or otherwise looks up to and envies. My personal favorite is Iron Man. He's charismatic, cocky and a genius. Plus, in the movies he's played by Robert Downey Junior...enough said. The real question, however, is what makes a true hero. Society labels a hero as 'one who shows great courage.' That can be, firemen, policemen, doctors, military personnel or even teachers (it takes a lot of courage to take on the jerks teachers have to deal with.) In class we've talked about literary heroes like Beowulf and Oedipus. They were seen as heroes due to their deed and accomplishments. They were well-known people (kings) who overcame a huge challenge or even fate, even if Oedipus did a pretty awful job of it.
Society sees heroes like fireman and policemen, at the same time they acknowledge Superman, Batman and Iron Man as heroes.So what is a hero?
I don't think that there is any true definition for a hero. I think that heroism is in the eye of the beholder. Anyone can be a hero, parents, teachers, dogs. Heroes are just ordinary people who do amazing things. i.e Iron Man.
