Hero

I looked hero up at dictionary.com. I got:

1. a man of distinguished courage or ability, admired for his brave deeds and noble qualities.
2. a person who, in the opinion of others, has heroic qualities or has performed a heroic act and is regarded as a model or ideal: He was a local hero when he saved the drowning child.
3. the principal male character in a story, play, film, etc.
4. Classical Mythology.
a. a being of godlike prowess and beneficence who often came to be honored as a divinity.
b. (in the Homeric period) a warrior-chieftain of special strength, courage, or ability.
c. (in later antiquity) an immortal being; demigod.
In my opinion, a hero can be somebody who has laid down their life for another, or place their life in danger for another.
I firmly believe one of the first symptoms of a hero is denial. I don't know how many times I've heard them say, "I don't think I'm a hero." "I was just doing what anybody else would have done."
I also believe many, but not all, heros wear uniforms. You can find many wearing military uniforms, fireman uniforms, police uniforms.
My dad was a hero. He sacrifice much so me and my siblings could have what we needed. Dad, if you can hear me. Happy father's Day!
