Constantine P. Cavafy - Walls

With no consideration, no pity, no shame,
they have built walls around me, thick and high.
And now I sit here feeling hopeless.
I can't think of anything else: this fate gnaws my mind -
because I had so much to do outside.
When they were building the walls, how could I not have noticed!
But I never heard the builders, not a sound.
Imperceptibly they have closed me off from the outside world.
