Sometimes, for a brief moment walking down the street, I find myself feeling all alone. A silence settles over me, and indeed the whole world; I am walking the earth after the Apocalypse, and I am the only human alive.

There's a sense of giddiness and glee there, I can do anything, go anywhere, and no-one will know, there's no one left to know.

Then a car passes on the road, the faint strains of an unsure pianists fingers reach my ears, a dog barks

And the illusion is shattered.
