It seems someone managed to spill some paint last night, but then not tell anyone about it, and now the entire side of the street is gradually getting white washed.
What I don't understand is how so many people managed to all walk through it, surely when you see the puddle and the footprints (that weren't there yesterday) you have to be suspicious. I know I was.
Anyway no-one seems to bothered by it now, we just have a white pavement and lots of interesting footprints everywhere. Perhaps this was just the base coat of a modern art street installation, and when I come back there will be lots of interesting reds and blues all over the place, who knows?
