It's like the song of a bird I recall from long ago, a tiny yellow bird with a voice like dancing water. Strange. I'd forgotten all about that bird, how she's wake me every morning at dawn, when I was still curled safely in my mother's nest.
I chose this quote because it brought to life the setting that the character's remember. I enjoy the simile for the bird's voice; it seems so peaceful. It is very different from the setting where the characters are currently: a zoo. I think perhaps the characters remember the setting a little more fondly than it actually was.
