Wall

Get hammers to destroy wall back in time and other walls- crows on them to fly to sky from them and trees spring in their broken bricks from future bird droppings.

Further birds will ingest their seed to demolish past walls to open sky to endless blue ,with brother to brother away, like crows from glass pieces sparkling as in kaleidoscope .

Dusk after cow returning dusk, their hoof dust blinds our sky.We go up and up in night stars. What we see is unbroken wall.
