Robert Laurence Binyon - Come back, sweet yesterdays!

Come back, sweet yesterdays!
Sweet yesterdays, come back!
Ah! not in my dreams only
Vex me with joy, to wake
From dream to truth, twice lonely,
And with renewed heart--ache.
Let night be wholly black,
So day have some kind rays.
Come back, sweet yesterdays!
Sweet yesterdays, come back!

Robert Laurence Binyon
