I had a very odd dream last night, one of those ones which seem to go on forever. Part of it involved a large old house and a strange stove, but that's a bit long winded.
The other part involved a road which we drove on when it was being built and then again once it was built; and each time, at precisely the same spot, a woman would be waiting and she would throw something made of solid plastic or metal, from her shoulder and onto the road right in front of us.
Twas only when I was relating the tale to Mr Zebra this morning that the pun hit me; we were driving along a road, and the woman was throwing a 'hard shoulder' at us...
No idea what it meant, nor what the rest of the dream meant either.
