Christina Rossetti - Promises Like Pie-Crust lyrics

Promise me no promises So will I not promise you Keep we both our liberties Never false and never true Let us hold the die uncast Free to come as free to go For I cannot know your past And of mine what can you know? You, so warm, may once have been Warmer towards another one I, so cold, may once have seen Sunlight, once have felt the sun Who shall show us if it was Thus indeed in time of old? Fades the image from the gla** And the fortune is not told If you promised, you might grieve For lost liberty again If I promised, I believe I should fret to break the chain Let us be the friends we were Nothing more but nothing less Many thrive on frugal fare Who would perish of excess
