Christina Rossetti Long Ago Quotations

Yet come to me in dreams, that I may live My very life again though cold in death; Come back to me in dreams, that I may give Pulse for pulse, breath for breath: Speak low, lean low, As long ago, my love, how long ago

Where are the songs I used to know, Where are the notes I used to sing? I have forgotten everything I used to know so long ago. ("The Key-Note")
