In the middle of the road there was a stone
there was a stone in the middle of the road
there was a stone
in the middle of the road there was a stone.

Never should I forget this event
in the life of my fatigued retinas.
Never should I forget that in the middle of the road
there was a stone
there was a stone in the middle of the road
in the middle of the road there was a stone.

Original Portuguese:

'No meio do caminho'

No meio do caminho tinha uma pedra
tinha uma pedra no meio do caminho
tinha uma pedra
no meio do caminho tinha uma pedra

Nunca me esquecerei desse acontecimento
na vida de minhas retinas tão fatigadas.
Nunca me esquecerei que no meio do caminho
tinha uma pedra
tinha uma pedra no meio do caminho
no meio do caminho tinha uma pedra.

Carlos Drummond de Andrade
