one day a man brought home a bird, every single day, the bird had produced the most wonderful songs he has ever heard, being a curious man, he decided he wanted to know what the bird was singing and wanted to know the words to this lovely song. 

The man stood high and low in the valleys and the depths of the  forests till he finally learned the language of 'bird' from an old wise woman. He was so happy he could not wait to get back home to hear what the bird sang.

When he got home, he listened to the bird sing, but ironically, it was not happy, because he finally realized that that tune is actually the bird weeping, wanting to be let out of its cage.

sniff sniff... sad eh? I was totally depressed when I heard this story... =(
