Quote context

[...]

- Butterfly, even one? Tell me that you saw only one?

- One? One alone, to be my own...

- Up goes downwind, up go down! Go and catch a falling star...

- It serves me right for even asking you. All butterflies know are songs and poetry and anything else they hear.

- I guess you mean well. Fly away, butterfly.

- Oh, I must take the A train.

- Oh, I am a cook and a captain bold and the mate of the Nancy brig.

- Has anybody here seen Kelly?

- I hope you hear many more songs.

- I must find someone who knows me, who has seen others like me.
