‘April is the cruelest month of all’ is taken from the work of-

April is the cruelest month, breeding
Lilacs out of the dead land, mixing
Memory and desire, stirring
Dull roots with spring rain.
Winter kept us warm, covering
Earth in forgetful snow, feeding
A little life with dried tubers.

- The Waste Land by T.S. Elliot.
