This morning when I walked to work, the fog was very thick and covered the world with a thin grey film.
The spires of this cathedral looked like they were evaporating into the fog.
But the fog was thickest over the river. The bridge I cross every morning disappeared into nothingness.
People emerged from the fog or disappeared into it as they crossed the bridge. I had a lot of fun pretending there was nothing on the other side and that I too would disappear as I walked into the greyness. Cool!
