Echo

I stumbled unpon this story when browsing through some greek gods after watching Hercules.
Echo is depicted as a person, a fairy or nymph actually, who lived in the woods and pranced around with other fairies throughout the forest. When one day she fell in love with a young hunter named Narcissus but could never aproach him. 
Echo was punished by Hera because she distracted her while Zeus "mingled" with other mountain nymphs. Learning of the betrayal Hera cursed Echo to only speak the last few words that someone else say.
When Echo returned to the forest she finally met with Narcissus but could not talk to him. 
When I hear this story I realize neverthing has a story and everything has a purpose. I liked this story in particular because even though Narcissus was handsom and young he ignored the influence of the other fairies and for some reason saw Echo. Its tragic because she died repeating Narcissus' last words. 
The kind of perosn I am really likes the back stories of certain characters. The reason there is a back story is to explain why something is what it is. I think we should use this in our art (no matter what kind; writing, drawing, or acting) because characters are not just characters, they should come alive and have an imprint on the viewer/reader.
