Mossy

This is not a brick wall, it's the floor on part of the Barbican highwalk.  The weather was rather uninspiring today, so looking down seemed more interesting than looking up for photos.

Really busy day at work - got too much to do!  Ended up staying an extra half hour this evening to get a couple of things finished, then went home feeling very tired.  I had a brilliant sleep last night, but I think it's going to take a few more to get me caught up properly.
