My business ...

... My business is to love. I found a bird, this morning, down - down - on a little bush at the foot of the garden, and wherefore sing, I said, since nobody hears ?
One sob in the throat, one flutter of bosom - "My business is to sing - and away she rose ! How do I know but cherubim, once, themselves, as patient, listened, and applauded her unnoticed hymn ?
