About this quote
Rossetti's speaker is describing the state of a heart the morning the beloved actually arrives, and the comparisons run from the bird to the apple tree to the rainbow shell. It is the most cheerful account of love waiting in an anthology of sad ones, and the reason it has been used for birthdays ever since.
