Echo and Narcissus

The story of Echo and Narcissus is most clearly presented as part of Ovid's Metamorphoseon. Echo was a nymph with a very beautiful voice, but Hera was angry, so she made Echo unable to say anything but to repeat the last thing said - just as the naturally observed effect of that name. She falls in love with a beautiful young hunter named Narcissus, but when she makes her affections clear, he rejects her. Apparently, rejection doesn't sit too well with the gods, so Nemesis, god of revenge, lures Narcissus to a pool. There he sees himself, not realizing that it was simply an image. He cannot leave the sight of himself, and he is either driven to suicide or turned into a flower depending on the version. Echo gets turned into only her voice, which explains why one hears echoes. This story only really serves as an origin story for echoes and the narcissus flower because we could only draw horrible lessons from these stories. Are we to understand that it is wrong to have a good voice and be talkative? Or that rejection is grounds for punishment? Narcissus wasn't even narcissistic by our standards because he didn't realize that his reflection was an image of himself. He cannot be blamed because he was indeed a beautiful youth.
