“I’m not gonna come down, down off of these clouds. All these heroes come and go, you’re still standing. You teach me to rise up, to open my eyes up. All these heroes come and go, you’re still standing. You’re still standing.” – David Cook
The meaning of this is that the person's hero is there forever. They aren't going to abandon them as did other "heroes". They're still there for the person and the person is showing that the hero is making an impact on them.
Beowulf showed this example by sticking up and being a hero to his own. He fought and never backed down.
My brother has been my hero since day one. He has always been there for me and still continues to be there for me. Ever since I was younger, he always showed me the right path of everything. If I ever seem sad, he will always work his ways to make sure I'm happy and caught up with life.
